Abstract
A series of exposure chamber measurements of the deposition of HT to snow were conducted at a field site. These experiments indicate that deposition velocities for conversion of HT to HTO are likely 10{sup -6} m s{sup -1} or less, which is approximately two to three orders of magnitude slower than deposition to soils under growing season conditions. Previous measurements of deposition to soil under freezing or near-freezing conditions also indicated very low deposition velocities. Deposition under winder conditions is thus likely to be much slower than deposition to soil under growing season conditions. It is concluded that exposure to HTO formed by the conversion of HT to HTO during a winter release of HT over snow or frozen ground is likely to be small compared to the dose from the HT plume itself.
