Abstract |
Dietary intake of radioactive substances ((134)Cs, (137)Cs, (40)K) from food in fiscal 2011--2014 was surveyed using the duplicate diet method. 1,612 diet samples were collected from general households of 18 prefectures. (134)Cs and (137)Cs were detected in samples from Fukushima Prefecture, Miyagi Prefecture and Tokyo Prefecture. (134)Cs and (137)Cs were detected in 11 samples in fiscal 2011, 12 samples in fiscal 2012, and 7 samples in fiscal 2013, but none was detected in fiscal 2014. The largest radioactivity in a sample was 12 Bq/kg in Fukushima Prefecture in fiscal 2011. The detected levels gradually decreased and were less than 1.0 Bq/kg in fiscal 2014. The maximum estimated dose of radioactive cecium was 0.14 mSv/year in fiscal 2011. Radioactive potassium was detected in every meal, and showed little change through the four years (median around 30 Bq/kg). |
