Wet-deposition processes for radioiodines
The results of a review of wet deposition processes for radioiodines are presented. Experimental measurements have shown that precipitation scavenging can be an important process for removal of radioiodines released to the atmosphere. Measurements of radioiodine species in routine gaseous effluents have shown that the distribution depends upon the type of nuclear facility considered. Because of differences in radioiodine species, observed scavenging rates for radioiodine in fallout are not generally applicable to routine releases from nuclear facilities. Adequate models are available to estimate the air to surface transport by wet processes. At the present time, the need is for more information on the rate constants used in the models. Reactor accident consequence calculations that assume no behavior differences among iodine species indicate that about half the predicted early deaths and illnesses are attributable to radioiodines. The distribution of species released under accident conditions will depend upon the actual sequence of events. However, for many scenarios the wet deposition of radioiodines will have an important bearing on the consequences.
