Environment Monitoring around Nuclear Reactors

All the ESLs are equipped with sophisticated nuclear instruments to detect extremely low-levels of radioactivity in the environmental matrices. These instruments include Gamma Spectrometers, Tritium counting units and whole body radioactivity counters. In addition to carrying out radioactivity measurements, the ESLs also carry out assessment of drinking water quality and sewage effluent monitoring as per the requirements of the pollution control board. To ensure the quality of data generated, the ESLs routinely participate in various quality assurance programmes conducted by international bodies such as International Atomic Energy Agency (IAEA). Inter-comparison exercises for measurements pertaining to various instruments are also carried out at the national level.

Experience of extensive environmental monitoring in the vicinity of nuclear power plants for the last several years (as seen in the figure below) has shown that the doses to the members of the public are far below the AERB limit of 1000 micro-Sv/year and negligible compared to dose received from natural sources which is about 2400 micro Sv/y. In view of this, no concern from the point of view of health risks to the general public arises.
