title: Fallout 3H ingestion in Akita, Japan.
abstract: To study fallout 3H ingestion in Japan, 16 separate food group samples were collected from Akita during 1985. The 3H concentration in free water and that in a tissue-bound form were determined separately. The average 3H concentration in the tissue-bound form was 2.2 Bq L-1, 1.7 times higher than in the free water of the food. The ingestions of 3H in the tissue-bound form and as free water in the diet were 0.60 Bq d-1 and 1.0 Bq d-1, respectively. Cereals represented the food group that contributed the most to the ingestion of tissue-bound 3H. Total 3H ingestion was estimated to be 4.1 Bq d-1. The contribution of the tissue-bound form to the total ingestion was 15%, considerably lower than reported for Italian diets. The ratio of 3H ingestion in the tissue-bound form to the free water form in the diet was similar to the ratio reported for New York City.
