Abstract

[…] This study aimed to provide an urgent estimate of the dietary exposure of adult residents recruited from three areas in Japan to cesium 134 (134Cs), cesium 137 (137Cs), and, for comparison, natural potassium 40 (40K) on December 4, 2011. Fifty-three sets of 24-hr food-duplicate samples were collected in Fukushima Prefecture and neighboring regions. The 134Cs, 137Cs, and 40K levels in the samples were measured using a germanium detector. Items in the food-duplicate samples were recorded and analyzed for radiocesium intake. Radiocesium was detected in 25 of 26 samples from Fukushima. The median dietary intake of radiocesium was 4.0 Bq/day (range <0.26–17 Bq/day). […] The estimated dose level of radiocesium was significantly higher in Fukushima than in the Kanto region and western Japan. Stepwise multiple linear regression analyses demonstrated that the intake of fruits and mushrooms produced in Fukushima were significant factors for the dietary intake of 137Cs in the 26 participants from Fukushima.
