Abstract

Since Fukushima Dai-ichi Nuclear Power Plant Accident, radioactive contamination in foods has been worried. Therefore, radioactivity concentrations of 134Cs and 137Cs in 100 processed foods of Japanese apricot marketed in Japan were measured by γ-ray spectrometry. Samples were bought from 2015 to 2016. 134Cs was detected in 6 samples, and the concentrations of 134Cs in them were in the range of 0.82 to 12 Bq/kg. 137Cs was detected in 40 samples, and the concentrations of 137Cs in them were in the range of 0.65 to 69 Bq/kg. The maximum total radioactivity of 134Cs and 137Cs in all samples was 81 Bq/kg, which was in an extract of Japanese apricot. The concentration in this sample was about four-fifths of the regulatory limit in common foods. The maximum total committed effective dose of 134Cs and 137Cs for adults by annually taking processed foods of Japanese apricot was estimated to be about 1.7 μSv.
