Rain scavenging of tritiated water a field experiment and theoretical considerations

, : Rain scavenging of tritiated water a field experiment and theoretical considerations. Atmospheric Environment 12(6-7): 1523-1530

An HTO rain scavenging experiment was performed under measured atmospheric field conditions. Dry deposition was minimized and undercutting of the plume by sampled precipitation was avoided. The observed removal rates were 9.5 and 6.7% h-1 at downwind distances from the source point of 400 and 800 m, respectively. These results agreed well with theoretical calculations made using the EPAEC [a computer model] gas scavenging code.

The tradition in tritium washout modeling is to unite the washout model with a Gaussian plume model describing dispersion of tritium vapour in the atmosphere. In the present study, an alternative approach is proposed. A numerical Eulerian model th...
