Abstract:

Monitoring data are used as a basis to examine the radiation conditions in Obninsk, including an analysis of the radioactive emissions from the Physics and Power-Engineering Institute and the Scientific-Research and Physicochemical Institute, the content of technogenic radionuclides in atmospheric air, soil, surface waters, and the components of agricultural natural ecosystems, and an estimate of the dose and radiation risk to the public. The monitoring results show relatively low levels of technogenic radionuclides in the environment, much lower than the admissable values. It is recommended that regular radiation monitoring of the content of tritium in surface and underground waters and also iodine isotopes in air near the ground at Obninsk be continued.

The total estimated dose, taking account of numerous pathways of technogenic irradiation of the public in Obninsk, is on the average about 10⁻⁵ Sv/yr, which corresponds to a negligibly low radiation risk, less than 10⁻⁶ under standard operating conditions of nuclear objects.
