Abstract
Secondary Ion Mass-Spectrometry was used to detect the isotopes 238U and 232Th in aerosols, sampled after damage of the “Fukusima-1” atomic station. The isotopes present only on the surface of the particles, so, fuel assemblages were melted, and they penetrated into environment through the gaseous phase without leakage of a solid substance in the form of primary aerosols. The presence of 232Th is treated as a sign of 233U production.
