Cesium-137 urinary excretion by northeastern (Pordenone) Italian people following the Chernobyl nuclear accident.

To estimate the radiological consequences in humans due to the Chernobyl nuclear accident (5 May 1986), we have determined both the 137Cs concentration in food and the 137Cs daily urinary excretion on 198 residents of the Pordenone area. The resulting experimental data have been compared with those estimated from the International Commission on Radiological Protection Publication 10A model (ICRP 1971) using a suitable dietary intake, and they were found to be in reasonable agreement.
