title: Tritium concentrations of blood samples collected throughout Japan.
abstract: Tritium concentrations were measured for blood samples collected from 20 cities throughout Japan during 1989-1990. The mean 3H concentration was found to be 1.4 +/- 0.4 Bq L-1 and 1.0 +/- 0.4 Bq L-1 (combustion water) for free water 3H and organically-bound 3H, respectively, excluding the abnormally high data of one city. The organically-bound 3H contents clearly depended on the latitudes of sampling locations, although the free water 3H concentrations showed no correlation with the latitudes. Organically-bound 3H is considered to be more suitable than free water 3H as an indicator of long time 3H exposure to human.
