Relationships between 137Cs activity concentration in wild boar muscle samples collected in all seasons and (a) 137Cs deposition on soil (log10 Bq/m2), (b) body length (cm), and (c) body weight (kg) inside the difficult-to-return zone (DRZ). Results of the regression analysis are based on mixed linear models using years as random variables and the adjusted coefficient of determination (R2) are shown in the figures.
