Description

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 area around nuclear power facilities. More specifically, the present invention relates to radiation (radiation) measurement system combined with public transportation (route buses) operating in the area around nuclear power facilities such as nuclear power plants. Capacity) It is equipped with a measuring device, a satellite navigation system (GPS, Global Positionimg System), a communication device, and an information output device to acquire radiation (capacity) measurement information and measurement location information in real time while operating the route. When a radioactive disaster occurs by building big data by accumulating it together with the acquired information acquired through the existing fixed environmental radioactivity measurement system (ERMS), the 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 area around nuclear power facilities that allows residents to be safely evacuated by providing a safer relief station and a safer route to the relief station in real time.

In general, when a radioactive disaster occurs due to an accident at a nuclear facility, the conventional disaster prevention system sets an area suspected of radioactive contamination as a radioactive contamination risk area and then evacuates residents within the radioactive contamination risk area while allowing access to the area. control, and dispatch a team of disaster prevention personnel to a radioactive contamination risk area to detect radioactive contamination in the area. If radioactive contamination is found during detection, the contamination location information is transmitted to the radioactive disaster prevention command and control center, and this information is sent to the radioactive disaster prevention command and control center. The radiation disaster prevention command and control center that received the information accumulates and organizes the received contamination location information, establishes a disaster prevention plan, and directs disaster prevention personnel to respond to the situation. In other words, the disaster prevention personnel of a conventional disaster prevention team dispatched to a radioactive contamination risk area each carry a portable radiation detector and a communication device, and each detection worker manually uses the portable radiation detector he or she carries. Detect radioactive contamination in the assigned area, and if radioactive contamination is detected through a portable radiation (activity) detector, information about the location is reported to the radiation disaster prevention command and control center using a communication device. This is a method of commanding and controlling responses to radioactive contamination risk areas based on situational information about the assigned area received from each team member.

These conventional disaster prevention systems for radioactive disasters are unable to respond quickly and accurately to the scope of the accident, the movement path of the radioactive cloud, and the evacuation route for residents.

In addition, recently, a database of radioactivity diffusion routes according to all weather conditions that may occur in the jurisdictional area in the event of a nuclear power plant accident has been established, and in the event of a radioactivity leak due to a nuclear power plant accident, a database of radioactivity diffusion routes according to weather conditions at the time of the accident has been established.

The reliability is very low, and when radiation contamination is detected, the detection location information is reported through the disaster prevention personnel's communication device, and the radiation (activity) precision analysis and measurement team that is deployed later will contact the soil corresponding to the detection location information. Not only is there a delay in taking practical and appropriate response measures to areas at risk of radioactive contamination due to detailed analysis and measurement of radiation (activity), but residents are evacuated to designated relief centers in the event of a radioactive disaster regardless of whether the relief centers are safe. As a result, there was a problem that safe evacuation of residents could not be achieved.

It consists of a central monitoring center that controls and manages; The central monitoring center stores the data received from the fixed environmental radiation monitor and the mobile environmental radiation measurement device according to a preset algorithm, constructs the stored data into big data, and then reports when a radioactive disaster occurs. Based on the built big data, it is safe to reach from areas at risk of radioactive contamination, areas where radioactive contamination can spread, aid stations in locations where radioactive contamination is possible, aid stations in locations safe from radioactive contamination, and each resident evacuation area to aid stations in locations safe from radioactive contamination. This can be achieved by a radiation (capacity) measurement system combined with public transportation operating in the area around a nuclear power facility, which analyzes the safe path that can be moved and generates and transmits a map displaying the analysis results.
