A radiation (capability) measurement system combined with public transportation operating in areas around nuclear facilities}

The present invention relates to a radiation (activity) measurement system combined with public transportation operating in the vicinity of nuclear power utilization facilities, and more particularly, to a radiation (activity) measurement system for public transportation (route bus) operating in the vicinity of nuclear power utilization facilities such as nuclear power plants. Equipped with a measurement device, a Global Positioning System (GPS), a communication device, and an information output device, it acquires radiation (radiation) measurement information and measurement location information in real time while operating the route, and transmits the acquired information When a radioactive disaster occurs by building big data by accumulating information acquired through the existing fixed Environmental Radioactivity Measurement System (ERMS), it is a radioactive disaster that occurred based on the built big data. It is about a radiation (activity) measurement system combined with public transportation operating in the vicinity of nuclear power facilities that allows residents to safely evacuate by providing a safe movement route from

In general, a conventional disaster prevention system in response to a radioactive disaster due to an accident in a nuclear facility sets an area suspected of radioactive contamination as a radioactive contamination risk area, evacuates residents in the radioactive contamination risk area, and simultaneously enters and exits the area. control, dispatch a disaster prevention personnel team to the radioactive contamination risk area to detect radioactive contamination within the area, and if radioactive contamination is found during the detection of radioactive contamination, the contamination location information is transmitted to the radioactive disaster prevention command and control headquarters, and these information The Radioactive Disaster Prevention Command and Control Headquarters, which has received the radiation, accumulates and organizes the received contamination location information, establishes a disaster prevention plan, and directs disaster prevention personnel to respond to the situation. That is, the disaster prevention personnel of the conventional disaster prevention team dispatched to the radioactive contamination risk area each carry a portable radiation (activity) detector and communicator, and each detection worker manually uses the portable radiation (activity) detector he or she carries. Detect radioactive contamination in the assigned area, and if radioactive contamination is detected through a portable radiation (activity) detector, report the location information to the radioactive disaster prevention command and control headquarters using a communicator, and the radioactive disaster prevention command and control headquarters It is a method of commanding and controlling responses to radioactive contamination risk areas based on situation information on the assigned area received from each team member.
