The heightened utilization of ionizing radiation for diagnostic and beneficial purposes, the expeditious progress in nuclear reactors, as well as the risks of radioactive waste have raised significant safety and health concerns for the people working with radiation and the general public. While some exposure to radiation is acceptable, radiation monitoring should be done to keep the levels of radiation exposure to a minimum. In this paper, we intend to monitor and measure the radiation levels that a specific area is exposed to using a radiation sensor, and to send the data to a cloud from where the values can be accessed by the concerned authorities. In order to meet the objectives we utilize GM counters, which are radiation sensors that detect and measure the amount of radiation present in the radiation environment. The GM counter is interfaced to a NodeMCU to update the detected and measured radiation to a radiation IoT platform that can store and retrieve data across a network. Further, a GPS module is interfaced with the NodeMCU to locate the location data of the radiation emitted from the radiation sources under such radiation environment. The radiation values are remotely monitored in real time through web server configured with the radiation IoT platform to remote monitor the radiation level and mapping the location of such radiations.
