Abstract

In a preliminary study, in vivo skull measurements and in vitro urine measurements of 210 Pb and nat U have been performed to find out the individual, chronic exposure to waterborne natural radionuclides of a small group of Finnish people. For their domestic water, the studied individuals use water from drilled wells containing elevated concentrations of natural uranium and its daughter nuclides ( 234,235,238 U, 222 Rn, 226,228 Ra, 210 Po, 210 Pb). Enhanced 210 Pb and 235 U activities were observed in several people. A positive correlation is observed between the U concentration in urine (μg d -1 ) and the number of counts (cpm) in the gamma ray energy peaks originating from the decay of 235 U and 234 Th respectively. Calibration of the detector setup and the determination of background sources are in progress.
