Description

  The present invention relates to an environmental monitoring system and method for centrally managing activity plans, activity support, and measurement data of various moving bodies such as monitoring cars in environmental radiation monitoring and nuclear safety and disaster prevention measures.

  Emergency environmental radiation monitoring is performed when an abnormal situation occurs in a nuclear facility such as a nuclear power plant that holds or handles a large amount of radioactive material, and a large amount of radioactive material is released outside the nuclear facility. It is a monitoring that is carried out in order to quickly obtain information on radiation and radioactive materials in the environment around the facility.

  In the event of an emergency, based on the Act on Special Measures against Nuclear Disaster, at the stage when a notification is received from a nuclear operator, normal monitoring will be strengthened, and information on the situation in the facility will be obtained from the nuclear operator, and the situation will change accordingly. Preparations for emergency monitoring will begin, and if an event indicating a nuclear emergency occurs, emergency monitoring will begin.

  Emergency environmental radiation monitoring predicts exposure doses and protects the health and property of residents by quickly collecting information on radiation and radioactive materials in the surrounding environment and information on the release of radioactive materials from facilities. Therefore, it is necessary to obtain materials for urgently determining necessary protective measures (evacuation, evacuation, administration of iodine, entry prohibition, food intake restrictions, etc.).

  For this reason, in an emergency, a local dispatch monitoring team is formed and dispatched as necessary to quickly collect information related to the release of radioactive materials around the facility, and specially equipped with portable monitoring posts and integrating dosimeters. By doing so, the dose rate monitoring and iodine monitoring of the predetermined area around the facility will be implemented.

  The technology to perform emergency environmental radiation monitoring in a predetermined area around the facility is to input the radiation dose information associated with the map, accident information and weather information at the radioactive material handling facility, and diffuse and diffuse the radioactive material. In order to obtain the soil contamination status and the radiation dose information for each region by the radioactive material that has been collected, and to obtain the radiation dose information, a portable terminal equipped with a position detection device, a radiation dose measurement device, and a wireless communication means associated with the map is used. There is a technique to use (see, for example, Patent Document 1). According to this technique, local and detailed dose information on a map can be grasped, and the distribution of radioactive materials can be easily known.

JP 11-326521 A

  However, according to the above-described prior art, information on radiation and radioactive materials is acquired at an arbitrary position on the map, so depending on the location of the mobile terminal, the information acquisition position may be biased and highly accurate radioactive It is difficult to obtain material distribution.

  In addition, in the event of an accident, the nuclear reactor mainly produces radioactive noble gases (Xe, Kr) and volatile radioactive iodine, the nuclear fuel facility mainly uranium, and the reprocessing facility mainly plutonium and cesium. -137 etc. are released into the atmosphere. These are diffused and diluted into the atmosphere at a high rate, resulting in exposure to the surrounding population. Therefore, it is necessary to implement monitoring that requires swiftness that is directly related to emergency measures and monitoring that requires scrutiny for precise measurement. However, according to the prior art, it is difficult to quickly and precisely place a local dispatch monitoring team in a necessary area.
