The vegetables grown in the two different fields 60 and 230km apart from the Fukushima Daiichi Nuclear Power Plant accident were examined after the accident to determine the concentration of
134Cs,
137Cs and
40K together with those of soil. For the edible part, the transfer of
134Cs and
137Cs was observed to potato tuber only in the field of about 60km apart from Fukushima Daiichi Nuclear Power Plant. The contamination of radioactive caesium(
134Cs+
137Cs)was less than 7Bq/kg-wet weight in tuber and that of soil was less than or equal to 1235Bq/kg-dry weight. As to the edible part of cabbage and lettuce grown in each field, the concentration of
134Cs and
137Cs was less than the detection limit. The concentration of soil in each field was 651Bq/kg-dry weight or less. The concentration of
40K of each field was nearly constant in vertical direction, however that of
134Cs and
137Cs showed the vertical distribution of which the highest concentration was observed at soil surface.
