FRACTIONATION OF RADIOACTIVE MIXTURE IN CHERNOBYL DEPOSITS AND PECULIARITIES OF BEHAVIOR OF ISOTOPES OF CESIUM (PREPRINT IBRAE-2017-02)

Preprint IBRAE-2017-02 

Panchenko Sergey, et al. 

Empirical data on the fractionation of radioactive elements emitted into the atmosphere as a result of the Chernobyl accident are systematized in the paper. With regard to volatile elements such as the isotopes of iodine and cesium, the fractionation factor varied from 0.5–0.7 to several thousands. When radionuclides were deposited on different surfaces under various weather conditions, differences between superficial fractionation factor and the air one were also noticed. The behavior of cesium isotopes in deposition among all the elements considered was the most unusual.
