“…In a bare soil sheltered from rain, Garland (1980) observed an evolution rather similar to this type. A similar fashion of an evolution could also be predicted in the rice experiment carried out by Choi et al (2000). It seems, however, that the peak of the profile descended more rapidly in the present experiment than in the rice experiment.…”

“…This increase is likely to have occurred solely by an increased accessibility of the radionuclides to the roots, unlike the case for HTO. Choi et al (2000) reported TF a values (m 2 kg À1 -dry) for OBT in different parts of rice plants grown in lysimeters treated with an HTO solution at different growth stages. Unlike the OBT TF a for Chinese cabbage, the OBT TF a estimated for the whole aboveground part of the rice plants decreased in the latest application, which was made at the yellow-ripe stage of rice.…”

“…As a parameter for quantifying the transfer of HTO from soil to plant, an areal transfer factor (TF a , m 2 kg À1 ) for either TFWT or OBT was calculated as follows (Choi et al, 1998(Choi et al, , 2000:…”

“…On the other hand, a considerable portion of the soil HTO can be expected to escape back to the air by evaporation and transpiration (Brudenell et al, 1997;Choi et al, 2000Choi et al, , 2005Garland, 1980). This process will affect farmers through inhalation and skin absorption of HTO vapor.…”

“…The existing studies mainly focus on the routine release and short atmospheric HTO exposure at daytime [4,[11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Little information is currently available regarding the tritium uptake and subsequent formation of organically bound tritium (OBT) in plants exposed to elevated levels of atmospheric tritium during the nighttime [24].…”

Potted soybean plants were exposed to evaporate HTO for 1 h inside an exposure box at two different growth stage (flowering and podding stage, filling stage) during nighttime and daytime. The concentration of tissuefree water tritium (TFWT) and organically bound tritium (OBT) in leaves and beans was measured at the end of the exposure. The results indicated that the quasi-equilibrium between the TFWT concentrations in the soybean leaves and the HTO concentration of the ambient air moisture required more than 1 h to be reached. The relative TFWT concentrations in the nighttime represent about 1/2 to 2/3 of the concentrations obtained in the day in the leaves compared to about 1/2 to 4/3 in the beans. The relative OBT concentrations under night conditions were about 2/5 to 1/2 of those under day conditions in the leaves, contrary to 1/2-7/10 for the beans. By developing tritium concentration assessment model with a short-term release of atmospheric HTO, we comprehensively considered the plant growth stage and the environmental conditions.
