IoT-Based Monitoring and Reporting System for Dosimeter Wearers in Radiation Areas

The utilization of radiation sources in a variety of activities has rapidly increased in today’s modern civilization. As a result, occupational exposure to ionizing radiation doses that cause health effects increases. Excessive doses of 20 millisieverts (mSv) per year cause acute effects such as sterility or cancer. Ionizing radiation has a negative impact on human health. In Tanzania, Dosimeters are managed by the Tanzania Atomic Energy Commission (TAEC) to lessen radiation risks for radiation workers. Nonetheless, after dispatching those dosimeters, the TAEC management room is unable to determine whether or not each supposed wearer has worn the dosimeter. This causes an incorrect assessment of an individual occupational radiation dose. As a result, a Dosimeter Wearers Monitoring and Reporting System for Radiation Areas was created using the Internet of Things (IoT). In the project, we propose an efficient and cost-effective method for real-time remote monitoring and reporting workers wearing passive dosimeters when nearby or in the region; radiation exposure is too high using IoT technology. System development was done using the scrum technique, which is based on agile methodology. An ESP32 microcontroller board that was C-programmed using the Arduino Integrated Development Environment powered the device. Through its internal Wi-Fi, the ESP32 microcontroller was able to transmit data to the web server. The end user (TAEC management officer) was able to monitor and visualize radiation workers thanks to the mapping web application. The developed system made it possible to track and report on the dosimeter.
