The study participants were divided into three groups mainly based on their diet. The first group comprised recreational fishermen and the second group represented people consuming more reindeer meat than an average Finn, while people using drinking water with very high activity concentrations of 210Po were selected for the third group. The fourth group was a control group. The mean urinary excretion of 210Po in groups 1 and 2 was 73 and 100mBqd−1, respectively. These values were higher than the value of the control group (20mBqd−1) and the mean values reported in the literature. The mean daily urinary excretion of 210Pb in groups 1 and 2, 70 and 52mBqd−1, was also slightly higher than that in the control group (32mBqd−1). In contrast, the excretion rates of both 210Po and 210Pb for the members of group 3 were one to two orders of magnitude higher than those reported in the literature. This was clearly due to the elevated levels of natural radionuclides in their drinking water. The present study demonstrates the importance of possessing good knowledge of the background levels, in order to allow the determination of the additional exposure due, for example, to the malevolent use of radiation.
