Release of <sup>137</sup>Cs into the gas phase during the interaction of <sup>137</sup>Cs compounds with molten lead

The release of137Cs into an Ar flowduring the interaction of137CsI and137CsOH—137Cs2CO3with molten lead at a temperature of ~852 Kwas studied.During the heating of Pb0with137CsI,137CsOH—137Cs2CO3, and137CsI—137CsOH—137Cs2CO3, from 2 to 8% of137Cs can pass into the gas flow. Based on the distribution of137Cs between the elements of the gas purification system, it was concluded that the chemical and disperse composition of compounds containing137Cs in the gas phase is quite heterogeneous. Volatile137Cs compounds formed upon heating137CsI,137CsOH—137Cs2CO3, and137CsI—137CsOH—137Cs2CO3with Pb0in a gas flow at ~852 K can contain both charged aerosols and aerosols without electric charge.
