CONTENTOF ^(210)Pb AND ^(210)Po IN MAIN FOODS OF HUNAN PROVINCE

本文报道了湖南省主要食品中^(210)Pb 和^(210)Po 含量的调查结果。所调查的17类食品中^(210)Pb 和^(210)Po的含量范围分别为0.02—11.8和0.04—15.6Bq·kg^(-1),由此估算出湖南省居民由食品摄入^(210)Pb 和^(210)Po 所致待积有效剂量当量分别为102.6和29.6μSv。

Investigation results were reported of content of ^(210)Pb and ^(210)Po in main foods of Hu-nan province from 1988 to early 1989.The content of ^(210)Pb and ^(210)Po in 17 kinds of foods investi-gated ranges from 0.02 to 11.8 Bqkg^(-1) and from 0.04 to 15.6 Bqkg^(-1) respectively.The estimatedcommitted dose equivalents of residents were 102.6 μSv and 29.6 μSv for ^(210)Pb and ^(210)Po being in-taken through foods respectively.
