Abstract

The removal of volatile 137Cs and 131I compounds from an air flow on various filtering elements was studied. 131I2 and 137CsOH are sorbed on basalt wool, but the degree of their recovery is low: ∼86 and 90–93%, respectively, at the basalt wool bed height of 15–18 cm. The use of a cascade of bubblers in combination with a column packed with basalt wool allows virtually complete (>99.9%) removal of 131I and 137Cs in the form of 131I2, 137Cs131I, and 137CsOH from an air flow.
