Radiocesium 137Cs, Bioindicators, Mosses, Bosnia and Herzegovina.

Anthropogenic radioisotope 137Cs had first appeared in the environment in significant quantities after performing atmospheric nuclear testing. The last two extremely large amounts of the radioacesium 137Cs were released in the atmosphere during the nuclear accident at Chernobyl in 1986 and in Fukushima nuclear reactor accident in 2011. This paper explored the levels of contamination of moss radiocesium 137Cs after almost 30 years since the Chernobyl disaster, which were obtained from 92 locations in Bosnia and Herzegovina. Gamma spectrometric analysis of the collected samples was performed using three high resolution of the purity germanium detectors with 35, 23 and 70% relative efficiency. 137Cs was present in all tested samples of moss, with concentrations of 137Cs ranging from 4 to 1612 Bq/kg dry weight of selected moss species.
