EVALUATION OF THE IRRADIATION DOSE RATE FOR MARINE BIOTA IN THE REGION OF THE DESTROYED FUKUSHIMA REACTOR (JAPAN) IN MARCH-MAY 2011

摘要

The irradiation dose rate in March-May 2011 is evaluated for marine biota in the coastal zone near the destroyed Fukushima reactor and in the open sea. It is shown that for representative marine organisms (fish and mollusks) the irradiation dose rate did not exceed the safe level 0.4 mGy/h (10 mGy/day). In the open sea, 30 km from the nuclear power plant, the irradiation of marine biota is much lower than in the coastal zone near the nuclear power plant. A comparative evaluation is made of the irradiation dose rate for water organisms in the exclusion zones of the Eastern-Urals track of radioactivity and the Chernobyl and Fukushima nuclear power plants.
