The concentration of uranium (U-238) in various foods containing radioactive cesium (Cs-134 and Cs-137) derived from the Fukushima Daiichi nuclear power plant accident was determined using inductively coupled plasma mass spectroscopy. U-238 concentration in the foods that Cs-134 concentration was below the limits of detection and that was obtained before the accident, were also investigated. U-238 was detected in all 87 samples investigated and the concentration ranged from 0.038 to 130 mBq/ kg. In addition, no correlation was observed between the concentration of radioactive cesium and U-238. The range of U-238 concentration observed in the post-accident food samples was similar to that in the food samples that Cs-134 concentration was below the limits of detection and that in the pre-accident food samples, and to the literature values in foods previously reported. These results suggest that the U-238 concentration was not significantly different in the foods between before and after the accident.
