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 105 times lower than the corresponding norms.
