RESUMO
BACKGROUND: The fallout of artificially produced radioactive isotopes has been recorded at a site in southern West Siberia (54°50'43.6â³ N, 083°06'22.4â³ E, Novosibirsk, Russia). DISCUSSION: The highest activities of (131)I, (134)Cs, and (136)Cs were found in fresh snow precipitated on 02 April 2011, at 0.83, 0.092, and 0.002 Bq L(-1) of meltwater, respectively. The (131)I/(134)Cs ratio decreased from 9.0 on 02 April to 1.2 on 27 April, which is consistent with the radioactive decay of (131)I. This fallout can only have originated from the accidental emission of Fukushima Nuclear Power Plant, Japan, in March 2011.
