Release of 137Cs into the Gas Phase during the Interaction of 137Cs Compounds with Molten Lead

The release of 137 Cs into an Ar flow during the reaction of 137 CsI and 137 CsOH– 137 Cs 2 CO 3 with molten lead at a temperature of ~852 K was studied. It was determined that during the heating of Pb 0 with 137 CsI, 137 CsOH– 137 Cs 2 CO 3 , and 137 CsI– 137 CsOH– 137 Cs 2 CO 3 from 2 to 8% of 137 Cs can pass into the gas flow. Based on the distribution of 137 Cs among the elements of the gas purification system, it was concluded that the chemical and disperse composition of the compounds containing 137 Cs in the gas phase is fairly heterogeneous. Volatile 137 Cs compounds formed on heating 137 CsI, 137 CsOH– 137 Cs 2 CO 3 , and 137 CsI– 137 CsOH– 137 Cs 2 CO 3 with Pb 0 in a gas flow at ~852 K can contain both charged aerosols and aerosols without an electric charge.
