The data from routine monitoring of persons working in French nuclear power stations was used to study the retention and urinary excretion of 137Cs in various regions of France over the three year period following the Chernobyl accident.
In order to minimise interference from less than detectable values, true means of the monthly measurements were preferred to arithmetic means.
We were able to deduce an equivalent biological half-time very close to that recommended by the ICRP and confirm that uptake and intake of cesium were very similar.
Within regions, in terms of measured activity, over a period of two years following the accident, we showed that intake during the second year represents one third of total intake and confirmed that the resulting internal exposure of the French population has been extremely low.
