Effective and environmental half-lives of radiocesium in game from Poland.
2021
For the first time changes in the 137Cs activity in game throughout Poland, including its most contaminated part known as the Opole Anomaly, were analyzed. Due to its long physical half-life, 137Cs continuously demonstrates high activity both in soil and biota. The species of game mammals, along with forest fruit and mushrooms, tend to accumulate this radionuclide, becoming one of the main sources of secondary contamination in people. In this study the 137Cs activity in roe deer, wild boar and red deer muscle tissue samples, within the years of 1986–2019, were studied. The effective and environmental half-lives were determined for each of the mentioned species for four regions including NE …
Levels of 137Cs in game and soil in Opole Anomaly, Poland in 2012–2020
2021
Abstract Once deposited, radiocesium remains in the environment for a long time, and constantly enters the food chain. Over time, game species tend to accumulate 137Cs by two orders of magnitude more than farm animals. This occurs especially in places heavily contaminated, thus meat products made out of local game should be treated with caution. One of such areas, known as the Opole Anomaly, is located in South-Western Poland and represents one of most 137Cs contaminated regions across Europe after the Chernobyl accident. The aim of the study was to find out the 137Cs activity in soil and local game, the value of the soil-to-game aggregated transfer factor and to assess the effective dose o…
