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.
