Radiation environment monitoring refers to the measurement of radiation and radioactive levels outside the perimeter of facilities operating radioactive substances, which is related to the operation of the facilities. The objects of radiation environment monitoring are environmental media and organisms. The purpose of radiation environment monitoring is to verify whether the radiation and radioactive levels caused by the operation of nuclear facilities in the surrounding environment comply with relevant national and local regulations, and to monitor the long-term changes in environmental radiation caused by human nuclear activities, including changes in environmental radiation levels caused by the redistribution of natural radioactive nuclides caused by human activities. The specific purpose and significance of environmental monitoring mainly include the following aspects: ① evaluating the actual or potential exposure level of radioactive substances or radiation released into the environment by facility operation, or estimating the upper limit of such exposure, and monitoring and evaluating its long-term trend to identify problems and improve them in a timely manner; ② Collect relevant data between the operating status of facilities and the process of pollutants entering the environment, as well as the level of environmental radiation generated. Pay attention to the discovery of unknown exposure pathways and release methods, or the impact of other release sources; ③ When an abnormal release or accident occurs, make a rapid response and provide a basis for evaluating the consequences of the accident and emergency decision-making through monitoring; ④ Prove that the release to the environment meets the requirements of corresponding regulations, provide relevant information to the public, and improve public relations
