Radiological and Environmental Safety Division (RESD) is responsible for carrying out R&D related to radiological and environmental safety of fast breeder reactor technology, environmental radioactivity monitoring and assessment within the site and survey and archival of terrestrial and marine biodiversity around the facility. Exploring application of ionizing and non-ionizing radiation to societal benefits is another vital area of research and RESD provides irradiation services for R&D in agricultural and medical fields for respective agencies. Further, RESD is providing excellent calibration services to all Gamma and Neutron monitors used by DAE units, DRDO, NDRF and other non-governmental industries using the accredited Regional Calibration Laboratory; engaged in environment radioactivity measurements in various matrices at its Nuclear counting Facility and testing of HEPA and Iodine filters of radioactive facilities in Kalpakkam units, NFC etc. All these service facilities are NABL accredited.
In order to create awareness among various sections of the public about the peaceful uses of nuclear energy, radiation safety and achievements of DAE in science and technology, a well planned public awareness program has been operational for disseminating the knowledge and advancements in the three stages of Indian nuclear energy with exhibition charts and demonstration models.
