title: Time-dependence of ¹³⁷Cs activity concentration in wild game meat in Knyszyn Primeval Forest (Poland).
abstract: Wild game meat samples were analysed from the region of the Podlasie province (Knyszyn Primeval Forest). (137)Cs content in meat was determined by gamma spectrometry in 2003 (33 samples), 2009 (22 samples) and 2012 (26 samples). The samples were collected in the autumn of 2003, 2009 and 2012 and were compared with data from 1996. Mean concentrations of (137)Cs in the respective years were as follow: 42.2 Bq kg(-1), 33.7 Bq kg(-1) and 30.5 Bq kg(-1), respectively. On the basis of mean values of (137)Cs in the meat samples of red deer (Cervus elaphus), roe deer (Capreolus capreolus) and wild boars (Sus scrofa) between 1996/2012, the effective half-life of (137)Cs was determined for specific species. For red deer equaled 8.9 years, for roe deer 11.6 years while for wild boar it exceeded the physical half-life and equaled 38.5 years. Mean value CR obtained for all three species equaled 1.7 ± 1.5 out of 102 measurements in animals muscles.
