Livers, kidneys and muscles of large herbivorous animals: the roe deer (Capreolus capreolus), red deer, (Cervus elaphus) and fallow deer (Dama dama), collected in Northern Poland, were the subject of our investigation. The radioactivity concentration of 238U ranged widely between 2.49±0.18 and 69.37±5.45 mBq·kg-1 w.w. There was no correlation between the accumulation of uranium and the analyzed tissues and organs. The values of 234U/238U activity ratio in analyzed samples were between 0.61±0.08 and 1.41±0.26, while most of the samples had ratios close to 1. The concentration of 239+240Pu in the analyzed tissues decreased in the order kidney > muscle tissue > liver. The average radioactivity concentrations of 239+240Pu ranged between 0.18±0.04 mBq·kg-1 ww in muscle and 2.77±0.60 mBq·kg-1 ww in kidneys. As statistically checked, the sampling location (ROLP Białystok, Gdańsk, Olsztyn, Szczecin, Szczecinek, Toruń), sex, age, and animal species did not influence the uranium and plutonium concentrations of the analyzed samples.
