Calculation of parameters of cs 137 release from a molten pool after the accidental melting of an ionizing radiation source

This paper aims to calculate the main parameters characterizing the release of Cs‑137 isotope from the molten pool after the accidental melting of an ionizing radiation source. These parameters include the fraction of Cs‑137 total inventory that is emitted in aerosol form, and the characteristics of aerosol size distribution. The presented results are obtained for the typical parameters of a melting crucible and a source of ionizing radiation in an incident that occurred at in Electrostal city on April 13, 2013 [1].

It is shown that the approach used in calculations makes it possible to perform quantitative assessments of the main parameters of radioactive aerosols, and reduces the number of uncertainties in analysesof radiological consequences of the accidents that results from unintended insertion of volatile radioactive materials in industrial crucibles.
