Radiochemistry Aims and scope

Abstract

Gas-phase UV photolysis of 131I-labeled CH3I was studied. CH3 131I (228 mg) is completely photolyzed within 5 min under the static conditions at room temperature in an argon atmosphere. The final radioiodine compound formed under these conditions is 131I2. The chemical composition of the final products of CH3I photolysis in air is more complex. Agglomeration corcystallization of the CH3I photolysis products with NH4Cl in the gas phase was studied. The results of this study suggest that the main final product of CH3I photolysis in air is a fine IxOy aerosol. In the presence of NH4Cl, formation of NH4 131I aerosols is possible.
