Radiocaesium levels in game in the Czech Republic.

摘要: Abstract The paper summarizes results of monitoring 137 Cs activities in game species roaming the woods over territory Czech Republic for time interval 1986–2012. Geometric means and other statistical characteristics were estimated from data sets on assumption log-normal distribution 2004–2012 where character had displayed no significant change. (in Bq/kg) meat were: wild boar 5.1, red deer 1.9, roe 0.77 feathered 0.14. mean value less frequent amounted to 0.36 Bq/kg. geometrical standard deviation (GSD) widely varied 1.6 21 studied species. Based mass activity dependence time, we assessed effective environmental half-lives decline. For deer, half-life was 2.9 3.2 years, 3.6 years respectively. 38 determined with large uncertainty it shows constant influx digestive tract boars. A statistically season-based level found boar. Higher winter spring are linked decreasing access naturally occurring food lower content (chestnuts, acorns, beech nuts), making grub around ground-deposited (often mushrooms higher activity). meat, most probably, due green diet winter. average annual committed dose population based estimates consumption between 2004 2012 insignificant, only 0.03 μSv.
