IoT-Enabled Intelligent System for the Radiation Monitoring and Warning Approach

,


Introduction
Te usage of devices such as cellphones, hand-held devices, smart LEDs, and laptops is being increased in homes and ofces. Radiofrequency electromagnetic rays (RF-EMRs) emitted by such devices are harmful to the brain and skin cells of infants, patients, and people having skin issues. Similarly, long-term exposure to RF-EMR is dangerous and has the ability to change the structure of specifc cells and molecules in brain tissues, bones, cerebrospinal fuid, and the skull. Such waves and rays are more dangerous for children, specifcally for infants, as they can absorb 50% more radiation than adults. Children and infants' cells divide quickly, giving radiation more opportunities to interrupt the organ system and cause cell damage [1]. RF-EMRs are all around us and are emitted by various devices, such as cellphones, base stations, and access points. Te intensity of carcinogen. When children are exposed to any carcinogen, they are at a higher risk than adults. Tumors developing in children may not be diagnosed until adolescence due to the usual delay between frst exposure and diagnosis of a tumor, which can take decades. MWR is very harmful to the fetus. MWR exposure can cause protective myelin coating that protects brain neurons to degenerate [6]. Terefore, a specialized mechanism should be developed to save children and infants from harmful radiations.
A research study on rats exposed to 3G mobile phone radiation for 45 days (2 hours per day) resulted in the reduction of the sperm count and modifcations in sperm tails [7]. Smart phones when operated in an ideal mode cause lower exposure than those operating at maximum power. Te specifc absorption rate (SAR) is a parameter that represents the rate at which electromagnetic energy is absorbed per unit of time by a specifc biological mass of tissue. In general, SAR is the human body's exposure to RF electromagnetic felds emitted from various sources such as cellular phones. Additionally, it is observed that the specifc absorption rate of mobile phones is higher than that of other RF sources. In order to calculate SAR, smart phones, automatic positioning systems (APSs), and head-like phantoms flled with tissue-equivalent liquid are used to assess the SAR for smart phones [8]. In this regard, SAR can be computed using several methods, such as the initial slope method, Box-Lucas method, corrected slope method, and incremental analysis method [9].
Over the past two decades, IoT has diferent modes of operations, such as access points, Wi-Fi devices, Bluetooth devices, infrared devices, smart trash bins, monitoring environment, IoT-centered irrigation systems, smart trafc control, and healthcare systems. Devices such as cellphones, hand-held devices (iPads and tabs), smart LEDs, and microwave ovens are increasingly being used in our homes and ofces. Such devices are harmful to the brain and skin cells of infants, patients, people having sensitive skin, etc., because these devices emit high frequencies of electromagnetic and other waves and rays [10]. An IoT-based architecture along with applications and security for the design and development with sensors in 6G is provided in [11]. Similarly, highfrequency radio waves and microwaves are dangerous and have the ability to change the structure of specifc cells and molecules in brain tissues, bones, cerebrospinal fuid, and the skull. Such rays are more dangerous for children, specifcally for infants, as they can absorb 50% more radiation than adults [12,13]. Moreover, skin darkening (tanning) and skin-burn happen when the human skin is exposed to high intensity sunlight that has infrared and ultraviolet radiation [14]. High exposure to ultraviolet radiation can cause skin cancer [15]. X-rays and gamma rays are more powerful and dangerous for health. Although these rays are dangerous for all humans, children are more sensitive to radiation, as is concluded by the UN Scientifc Committee on the Efects of Atomic Radiation [16]. Continuous monitoring would substantially assist in taking preventive measures such as raising an alarm in the event of an incident. As a result, many countries throughout the world have suggested creating a variety of ways for monitoring the amount of radiation in the environment to detect any aberrant releases or discharges.   Mobile Information Systems Te author in [17] presents a survey that highlights the most relevant healthcare-based Internet of things (H-IoT) applications assisted by smart city infrastructure with the help of new technologies and tools to provide services based on several models with the best use of low-cost sensors, hence focusing on the possible research challenges along with the opportunities in this research area. Moreover, the recent elaborations in terms of sensing principles, sensing integrated with RFID (radiofrequency identifcation) technology along with its advantages and disadvantages, the scattering behavior of electromagnetic waves, and the bad efects of EMI (electromagnetic interference) on medical devices and patients who depend on these devices are reviewed and listed in [18][19][20][21][22][23].
Tere are various methods for monitoring and analyzing efects related to high-energy electromagnetic radiation as described in the radiation early warning system (REWS) [24]. Te REWS is made up of multiple electromagnetic detection sensors that are dispersed around a specifed area for monitoring radiations and ringing an alarm on longterm exposure to high electromagnetic radiation. Typically, established threshold values are used to determine alerts, which are based on observations (i.e., experience).
Existing REWS are time consuming, labor-intensive, and risky. In fact, when an alarm is produced, the system spends a signifcant amount of time and efort analyzing metrics derived from the meteorological datasets to evaluate the alert as true or false. Due to the absence of automation, these systems cannot usually classify the alert right away because they must wait for more gamma ray data to determine if they get back to normal.
Currently, there is no available tool approach at homes that can detect and process the dangerous intensity levels of electromagnetic waves, which are hazardous to infants and patients with sensitive skin according to a layman observation. Terefore, there is a dire need of developing an IoTenabled intelligent system for radiation monitoring and warning using machine learning, which uses a set of cheap sensors and IoT technology to protect infants, patients with burns, patients having low immunity, and patients having any kind of skin allergy. In this paper, researchers introduce a system that is based on the IoT concept using electromagnetic radiation sensors, which detect the intensity of electromagnetic radiation.
In this paper, researchers after collecting the sensor's data have used the decision-making power of decision trees for further processing and analysis of the data according to diferent situations. Te results show high accuracy and prove that our system is reliable and accurate for the detection and monitoring of radio waves. Te main contributions of this study can be summarized as follows: (i) It is the frst attempt to combine diferent machine learning models by incorporating a decision support system that assists IoT-based radiation detection and processing systems; (ii) the proposed method outperforms classical machine learning methods; (iii) the study found that the adaptive boosting classifer has the best accuracy of 81.7% among logistic regression, support vector machines, extra trees, bagging trees, decision trees, Gaussian naive Bayes theorem, and random forest classifer algorithms.
Te rest of the paper is divided into the following sections: Section 2 is about the related work, Section 3 presents the research methodology of the proposed system, Section 3.4 describes the implementation details of the system, Section 4 displays the results, and Section 5 is about the conclusion.

Related Work
Te authors in [25] have proposed a new sort of radiation monitors known as CROME (CERN RadiatiOn Monitoring Electronics). Tese monitors have embedded computing capabilities that allow them to run algorithms, such as calculating the true electric current created by electromagnetic radiation (EMR) detectors on exposure to ionizing felds. Tis paper gives a case study of a new approach for femtoampere current ofset correction. Te measured current is sensitive to the surrounding environment at this scale, such as temperature, vibration, and air permittivity. A novel method based on the deep neural network approach is proposed to provide high accuracy in performing real-time operations along with overcoming the restrictions of the feld-programmable gate array (FPGA) platform. Te neural network improves the accuracy by 7.31 percent and reduces the complexity by 42.9 percent. Hence, the results in terms of computational complexity are quite promising.
A theoretical approach comprising four tissue layers of the human head and a smart GSM-based cellular phone located at a distance of 2 cm from the human head is used to assess SAR values, electric feld strength, impedance, conductivity, and power density in the human head. Te results show that the SAR values at the skin layer are higher than those at the head layers [26].
Moreover, to address security issues during the communication of sensors' data, various machine learning algorithms, namely, naïve Bayes, linear regression, random forest, adaptive boosting, gradient boosting, decision tree, artifcial neural network, support vector machine etc., have been exploited for measuring the accuracy and detecting the botnet attack. Te results reveal that tree-based models achieved higher accuracy (>99%) than other models using the same sensors [27].
Te authors in [28] proposed the EMR-monitoring system for detecting and monitoring radiation in the surroundings of research reactors in China. Based on the necessary data on monitoring points of four typical research reactors in China, a summary and analysis of the current condition of supervised monitoring of radiation felds, such as monitoring subjects, points, and frequency, was completed. Te controlled monitoring of China's nuclear plants was examined in terms of past experiences and current issues. Tips on how to improve the monitoring of the radiation environment near research reactors have been noted. Te usage of biomedical and electromagnetic sensing mechanisms integrated with RFID technology in healthcare systems is systematically reviewed by the authors in [29].

Mobile Information Systems
Multiple types of passive radiation protection systems based on diferent ionizing radiation detection mechanisms were subjected to extensive performance testing due to the need for passive radiation protection harmonization and the requirements of international standards in the context of environmental monitoring in radiation protection. In this research article [30], the reaction of 12 distinct passive dosimetry systems from 9 institutions was evaluated as a function of the dose, energy, angle of photon incidence, and response to a natural radiation feld (gamma radiation of a sealed Ra-226 source) as part of the preparedness project. OSL and RPL-based systems outperform all other passive dosimetry systems tested in this study in every test. Te calculated statistical uncertainties of the instruments' readings were less than 10% for the majority of the experiments; however, two TLD systems and one flm system (J, L, K) have signifcantly greater statistical uncertainties. Te average angular response of the tested systems (excluding K and L) is between 0.8 and 4.5 percent, according to the fndings. Diferences in the measured data are caused by the employment of various detectors, holders, calibrations, measurement processes, and uncertainties. To establish valid and consistent dose measurements across Europe, prior investigations and standardization of passive radiation protection equipment are required.
In another study [31], the authors have presented the recent advancements in mobile radiation detection since the Fukushima nuclear accident, which is based on four scenarios, (a) radiological and nuclear emergencies, (b) illicit trafc of radioactive materials, (c) nuclear and irradiation services, and (d) naturally occurring radioactive materials.
In [24], a radiation early warning system is proposed that monitors the amount of gamma radiation in the air. Such systems require a lot of manual involvement and rely on expert analysis. Tis study has made this process autonomous while still allowing the user to make the ultimate decision. Te important feature of this research includes data preprocessors, incident extractors, incident classifers, and data enhancers. A new strategy is ofered for making the system more intelligent while also boosting the system's learning from previous experiences.
Te authors in [32] describe the tool named commercial of-the-shelf (COTS) that is based on a remote sensing monitor for a nuclear storage scenario to detect both hydrogen concentrations and temperature with the help of two procedures: (1) improvement of a compact, cost-efective, and robust sensor system and (2) validation of the remote sensor system. A radiation monitoring system is proposed that collects and records nuclear radiation exposure to the facility and its surroundings in the Yogyakarta Nuclear Area (YNA). An Internet of things-based radiation area monitor was created to increase the system's ability to not only measure radiation exposure but also send the data to a cloud server over the Internet. In the nuclear emergency response and readiness system, dispersed radiation data can be used to determine nuclear emerging potential. Te area monitor system is a sensor network that includes a Geiger-Muller detector with high-voltage power supply, a signal-conditioning system, an Arduino counter, and a data processor. Te detector collects data, which are then transferred to the server through a wireless network utilizing the node MCU communication module. Te receiver station system was created to collect data from a database server to display radiation exposure to the environment and determine whether or not there was a radiological emergency. According to the chi-square test and the stability technique, the constructed device has good stability with a probability of 0.75. Sr-90 and an X-ray spectrometer were used as radiation sources in validation tests, and the constructed device was compared with a typical survey meter. Te mean square error of this validation testing was 0.37 and 0.24 for Sr-90 at two diferent source distances, respectively, while the mean square error of the X-ray spectrometer source was 2.48 [33]. Te technology can be linked to a smart meteorological system to create an integrated data collecting system for the Yogyakarta Nuclear Area's nuclear and radiological emergency preparedness system. Similarly, a generative adversarial network (GAN) model based on intelligent data analytics can efectively recognize the music data to convey emotions and achieve the accuracy greater than 87% [34]. Another study revealed that the gradient boosting model (GBM) showed optimistic performance in predicting the rate of evaporation over two remote regions; thus, it may support stakeholders to manage water resources efciently [35].
A radiation monitoring system based on a microcontroller is presented in this research [36]. Te system calculates an accumulated radiation dosage over time and sends out alarms when the rate of the appropriate dose surpasses a particular threshold. A prompt response to emergency situations, such as exceeding the authorized power of the equal radiation dose and accumulator charge regulation, ensures the system's excellent reliability. In addition, the authors created an electronic circuit for the radiation monitoring system using a microcontroller. Additionally, an operational algorithm as well as software for the Arduino Uno board's ATmega328P microprocessor has been developed.

Materials and Methods
Te proposed system has the ability to predict the outcome of harmful rays on the body of human beings. For this purpose, sensors are connected to mega Arduino to take the data of radiation intensity from surroundings so that the intensity levels of rays can be checked. Infrared sensors, ultraviolet sensors, electromagnetic sensors, and gamma radiation sensors are connected to mega Arduino, and data are collected by the system and converted to data fles for further use. Tis approach is based on an intelligent decision-making system to verify the safe and dangerous levels of intensity of rays. All the data stored in Excel sheets and the system alert the user through an Android mobile application when the intensity level of rays becomes dangerous. Te overall design of hardware integration of the proposed system is shown in Figure 2.
Te proposed radiation detection system is based on the basic seven-layered architecture.
Te frst layer is called the application layer comprising IoT applications along with actuators, and the second layer is called the management layer having all functions related to device management and database management. Te third layer is a networking and connectivity layer based on networking components. Device perception is carried out through sensors and microcontrollers. Te fnal layer comprises machine learning models that provide the fnal decision results for the system. Te overall layered architecture of the proposed model is shown in Figure 3. Te radiation detection system uses the intelligent decision-making system to verify the safe and dangerous levels of intensity of waves. All data are stored in the database, and the system alerts the user through an android mobile application when the intensity level of waves becomes dangerous. Tis system consists of three basic modules, i.e., a module for data collection, a decision support system, and an output module.

Sensor-Based Data Collection.
Data collection through sensors is the frst step in the proposed system, such as electromagnetic wave intensity through electromagnetic wave sensors and ultraviolet wave intensity through ultraviolet wave detection sensors. For the data collection process, sensors were connected to the Arduino Mega microcontroller. Electromagnetic wave sensors and ultraviolet sensors are connected to the microcontroller through analog ports of Arduino. A microcontroller works as a central point that takes inputs from sensors and transmits the data from sensors to the decision support system. Te decision support system sends the data to the database after performing some action on the data. Ten, the data are sent to the user through smart devices.

Predictive System.
Predictive modeling is a statistical process that uses a probability distribution to forecast the output. Prediction was used to build models. Tese predictors are basically the variables that make up future results. When data were collected from various variables, a statistical model was designed based on probability. In this regard, researchers used diferent machine learning classifers, i.e., logistic regression, support vector machines, naïve Bayes, random forests, bagging trees, extra trees, decision trees, and adaptive boosting.  Mobile Information Systems cleaned data comprising 21987 pulses that were necessary for the optimized performance. Te former data with missing values are used as baseline data for further processing and model evaluation. Te detail of the dataset with respect to each sensor and radiation is given in Table 1.

Trained
Model. Te trained model contains all characteristics, which were validated while constructing the model with the training dataset. Te trained model (knowledge base) performs like the brain while testing with high accuracy and efciency. While compiling and executing data, some of the facts and rules were not modifed themselves. Tere were some facts that relate to the entire system's specifc consultation. Tese facts extend themselves to generate diferent decisions in the operational phase along with static knowledge. Overall, the trained model was trained with related knowledge, which is very helpful in understanding and solving problems. Te present study used 30% data for testing and 70% data for training.

Te Predictive Model.
Predictive modeling is a statistical probability process that uses various statistical methods, such as correlation matrix, probability distribution, and testing of hypothesis, to forecast outcomes based on decision rules. Te graphical representation based on the decision rules (Table 2) for electromagnetic radiations is shown in Figure 4.

Output
Module. An Android mobile application is developed for the IoT-enabled intelligent system for radiation monitoring and warning (ISRM) so that the user can get alerts when these harmful rays are present. Te basic controls of applications were put in tabbed menus. Te user gets access to the main features of the application such as dangerous radiation monitoring in neighborhoods of the user.

Implementation.
In the development of the proposed system, less expensive and tiny sensors were used technically to sense the presence of harmful rays. Te microcontroller consists of 16 analog input pins and 54 digital input/output pins, of which 15 can be used as PWM output, a 16 MHz oscillator, a power jack, a USB connection, a reset button, and an ICSP header. Sensors were connected to a microcontroller through jumper wires to access the data from sensors. Ultraviolet sensor UVM-30A was used to detect ultraviolet radiation, and Electromagnetic Wave Sensor V3.0 was used for the detection of electromagnetic wave strength. Te purpose of using the electromagnetic wave sensor in the proposed work was to check the presence of radio waves and measure the strength of radio waves. It detects the radio wave in its surroundings and covers a small range of radio waves. Tese two sensors were involved with Arduino Mega 2560. In implementation, the electromagnetic wave detection sensor was connected to the Arduino Mega microcontroller. Te electromagnetic wave sensor 5 V pin was attached to the Arduino 5 V pin, the output pin was attached to the A1 pin of Arduino, and the GND pin of the sensor was attached to the Arduino GND pin using jumper wires. After confguring the electromagnetic wave sensor with Arduino, Arduino IDE was used to write the code.
For coding, Arduino IDE is used. In implementation, Arduino IDE Version 1.8.8 was used for programming and hardware confguration. However, for getting the desired output of the sensors' data, the code was customized. Te C language was used for writing the code in Arduino IDE; then, this code was uploaded on the board, and the output was displayed on the serial monitor. Data on both sensors were collected in Excel sheets.

Recording Sensor Data.
Te data from the sensor appear on the serial monitor of Arduino. For storing data in Excel sheets, PLX-DAQ software was used. It was used to store the real-time values of sensors. Te data on sensors were collected in Excel sheets for diferent scenarios, such as low, moderate, and high intensity of rays. Te values of electromagnetic wave sensors were stored in percentage, and values of ultraviolet sensors were stored in indexes. Initially, the sensor produces data in voltage and then calibrates the raw data into proper units.
Python-based Jupiter Notebook is open-source software. It generates the accuracy for the prediction model. Unbalanced classifcations represent a challenge for predictive modeling since for most classifcation machine learning algorithms, the same number of examples has been developed for each class (minority and mainstream class). Tis leads to poorly predicted models, particularly for the minority class. Moreover, the prime focus is on the minority class as it generates more classifcation errors as compared to the mainstream class. Terefore, the dataset was balanced by eliminating outliers in this research. From the statistical perspective, the correlation matrix basically represents the relationship between dependent and independent quantities (x on y and y on x) as well as their positive and negative relationships.
An intermediate result called the correlation describes the best of the linear associations. Te correlation describes the strength and direction of the linear (straight line) correlation is denoted by r as shown in Equation (1), varying from +1 to −1.
where r is the nature of association, x is an independent variable, and y is a dependent variable.

Adaptive Boosting Classifer.
To solve classifcation problems (discrete data) and regression problems (continued data), the adaptive boosting classifer was adopted by researchers. Te AdaBoost algorithm's (see Algorithm 1) main principle is to combine many weak classifers in order to create a strong classifer. A group of base classifers is sequentially trained in this method. Te mistake of previous classifers is used to train each base classifer. Weights are modifed during the training process so that if a prior weak classifer misclassifes samples, the classifer's weight is increased (while the weights of correctly classifed samples are decreased). In each training phase, this form of weight change drives base learners to focus on diferent data, resulting in highly efcient and diversifed classifers. It reduces the residual value (diference between actual and predicted) by choosing an appropriate function that points towards the negative gradient. In hypothesis boosting, diferent steps were involved to observe the trained data that are applied to algorithms. Tese observations were strictly analyzed so that the newly created learner model can be tested on a set of poorly classifed data. Tis idea is based on AdaBoost (adaptive boosting). In this    Mobile Information Systems regard, various decision trees were built based on a single split (parent/child relationship). Te weighted mean of observations/instances are measured based on trained data to apply them to algorithms. In this way, many weak learners are added by reducing the loss function in the system in a linear way. In AdaBoost, the weak learner model associated with the class gives the best prediction votes. With the maximum votes, the new model is predicted. In the weighted minimization context, gradient boosting classifers and weighted inputs are recalculated. Diferent steps are involved when AdaBoosting is applied. In the frst step, the diference between the actual class value and the predicted class value is obtained to minimize the residual value. Tis classifer produces a future production model by assembling the weak learner model (decision tree) into a strong model in a sequential manner. Tis algorithm works 70% on training and 30% on testing proximal data. It also reduces the overftting of discrete data. Te fnal output classifer is expressed as follows: where sign (f (x)) is a function that convert values into actual classes, β m is a parameter controlled by how each weak base learner is added, and b m is base learning controlled by parameter m.

Extra Trees.
Decision tree is used because it is very easy to understand and make decisions, and it can be applied on large datasets. Furthermore, it does not require previous knowledge for making decisions rather it splits the datasets into training and testing. And a large number of single split decision trees are generated from the training dataset. Predictions were made by applying the statistical measure to the prediction of decision trees using maximum votes in the case of the discrete dataset (classifcation). It has achieved an accuracy of 79.166% to classify the efects of electromagnetic waves. Te fnal output classifer is expressed as follows: where ϵ(x) is the base learner and T is the number of base learners.

Bagging
Trees. It uses a collaborative algorithm planned to recover the accuracy of machine learning algorithms used in statistical methods. It has shown the correctness of 81.25%, while extra algorithms, i.e., random forests, support vector machines, Gaussian naïve Bayes, logistic regression, and decision trees have shown an accuracy of 80, 77,76, 79, and 71%, respectively. Figure 6 shows the confusion matrix  Step 1: Initialize weights: Step 2: Iterate the function from t � 1 to M for generating the training dataset by sampling Step 3: Fit some weak learners g t ( x → ).

Te fnal output classifer is shown in Equation (3) with updated parameter values.

Results and Discussion
Te proposed approach is unique and smarter because it uses the decision making ability of the decision tree model and takes its advantages. It was a new idea to use the intelligent approach for a sensor-based radiation detection system along with real-time sensing data. Te architecture and implementation details of the proposed system are elaborated in the previous sections. Te intelligent system consists of multiple sensors, diferent hardware and software modules, and a trained model (knowledge base) with a set of predefned rules and datasets of facts gathered by wave sensors. Te trained model was tested by using a rule-based inference engine with new data entries. Te performance tests of the proposed system were taken using two sensors (an electromagnetic wave sensor and an ultraviolet wave detection sensor) by embedding them into the test felds. Te sensors provide the real-time input data, which are forwarded to Excel sheets, decisions are taken based on those data, and the results are shown to an Android mobile application so that in response, the user can take some actions for their safety. Te calibrated output of sensors is processed with various machine learning algorithms, and the best accuracy is obtained by the adaptive boosting classifcation algorithm.
Te experimental results comprising the testing accuracy and validation accuracy are shown in Table 3. Radiation intensities are classifed after applying decision rules to the dataset, and the results are shown graphically in Figure 5. In the present section, all experiments are performed using the Python programming language. Researchers evaluated the model accuracy using those data. Figure 5 shows the validation accuracy for each machine learning model to predict the dangerous outcome of these waves. Dependent and independent features were given as inputs in machine learning algorithms; the output was used as a prediction future model. In the light of statistical methods, these analytical variables were used to solve statistical equations. Based on these all scenarios, target class/label values were categories because the label contains the target value for the machine learning classifers based on the training dataset, and to make a forecast model of any class, then you should split the dataset into the training dataset (70%) and the testing dataset (30%).

Comparison with State-of-the-Art Studies.
Tese results obtained through the proposed model are also compared with those of the recent related studies, as shown in Table 4. In [11], the authors have developed a new generation of radiation monitors known as CROME (CERN RadiatiOn Monitoring Electronics). Tese monitors have embedded computing capabilities that allow them to run algorithms, such as calculating the true electric current created by using radiation detectors when they are exposed to ionizing felds. Te results revealed that the system could not respond to evolving environments, such as indoor and outdoor areas. Moreover, this study requires more improvement in results. In another research [12], the author examined the supervised mode, monitoring basis, and monitoring system of radiation environment monitoring for typical research reactors in China. In this study, hazardous radiation levels were not identifed. Te author in [13] evaluated the reaction of 12 distinct passive dosimetry systems from 9 institutions as a function of the dose, energy, angle of photon incidence, and response to a natural radiation feld (gamma radiation of a sealed Ra-226 source) as part of the preparedness project. In this study, there was a high measure of errors. In [10], the authors proposed a radiation early warning system that monitors the quantity of gamma radiation in the air. Such systems require a lot of manual involvement and rely on expert analysis. Tis study has made this process autonomous while still allowing the user to make the ultimate decision. Tis study, however, does not include any fully automated system and requires human intervention. In another paper [37], a radiation monitoring system is proposed that collects and records nuclear radiation exposure in the facility and its surroundings in the Yogyakarta Nuclear Area (YNA). An Internet of things-based radiation area monitor was created to increase the system's ability to not only measure radiation exposure but also send the data to a cloud server over the Internet. However, this system requires a lot of resources.
Te proposed study refers to the employment of sensors that detect hazardous radiation and classifcation of these radiations with an adaptive bagging classifer. Experiments were carried out in various ways by employing other stateof-the-art machine learning algorithms, including decision trees, SVMs, and bagging classifers. Dependent and independent features were given as inputs in machine learning algorithms; the output was used as a prediction future model. In the light of statistical methods, these analytical variables were used to solve statistical equations. Based on these all scenarios, target class/label values were categorized because the label contains the target value for the machine learning classifers based on the training dataset, and to make a forecast model of any class, then you should split the dataset into the training dataset (70%) and testing dataset (30%). Tis implementation provides satisfactory results for the employment of the system.

Conclusion and Future Directions
In the present age, human beings are surrounded by many dangerous radiations. Tese radiations badly afect human health, and especially, these rays are very dangerous for infants and patients having skin diseases as well. Moreover, these radiations cause many diseases from simple infection to deadly diseases, such as eye infections, headache, skin tanning, skin burns, brain tumors, breast cancer, and skin cancer. Similarly, these radiations should be avoided, but one cannot feel the presence of these rays around oneself. Terefore, there is a need for such a system which can detect the intensity of rays around us. In this paper, a low-cost radiation outcome predictive system is introduced that is based on sensors. Te model adopted by the present study uses diferent machine learning models, and the study found that the adaptive boosting classifer is the best with an accuracy of 81.7% among others, such as logistic regression, support vector machines, extra trees, bagging trees, decision  trees, Gaussian naive Bayes theorem, and random forest classifer algorithms. In the future, it is recommended for researchers and scholars to use the Raspberry Pi microprocessor in order to increase the efciency of the system instead of the Arduino Mega microcontroller. It is a new technology and has its own processing power, USB ports, built-in Wi-Fi, and Bluetooth modules. Hypertuning and optimization techniques can be efective in improving the performance of models.
