青森県六ヶ所地区で採取した農産物, 海産物の¹⁴C比放射能

抄録

We investigated¹⁴Cspecific activity of farm products and marine products which were collected from the Rokkasho area in Aomori prefecture from 1988 to 1990. The measured¹⁴Cspecific activity of farm products was almost equal to one another with the averaged¹⁴Cspecific activity of 0.261 (Bq/g·C) .
On the other hand, ¹⁴Cspecific activity of marine products was slightly lower than those of farm products. Especially that of squid was the lowest among studied marine products. This may be due to the low¹⁴Cspecific activity of the sea water surrounding squid.
