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. © 2011 Springer Science+Business Media, Inc.

The results of 131I, 137Cs, and 134Cs measurements in the South Sakhalin atmosphere performed with a gamma spectrometer placed in a mobile radiation surveying laboratory are presented. The measurements were performed in March-April 2011 as part of radiation monitoring performed by Rosgidromet in connection with the Fukushima-1 accident in Japan. The maximum recorded 131I volume activity of inhaled air in South Sakhalin is 8700 times lower than the admissible yearly-average value for the general public. The values for 137,134Cs are 10 5 times lower than the corresponding norms. © 2012 Springer Science+Business Media, Inc.
