I want to get information about monitoring stations outside nuclear power plants. In relation to the standards and equipment used. Also , the distance that the station will be built and other necessary conditions that must be met
The USNRC (https://www.nrc.gov/docs/ML0913/ML091310141.pdf) requires the operators of nuclear power plants to have a Radiological Environmental Monitoring Program (REMP): typically, measurements are made at five stations: three near the plant boundary in the direction of most likely wind transport; one in the vicinity of a community likely to have the greatest chance of exposure; and one at control location 15 to 30 km distant in the upwind direction of prevailing winds (NUREG 1301). Radioiodine is measured weekly and gross beta activity of particulates captured on filters is measured quarterly. Analyses to identify gamma-emitting radionuclides are done on composite samples weekly.
