Follow-up of an old plutonium contamination case

The follow-up of a more than 25-year-old contamination case has been investigated since 1990 with improved accuracy for the measurement of the activity in the urine. Estimates of the body burden are based upon the late urinary excretion and the excretion factors given by Leggett. The case has also been proposed for the second European intercomparison organised by EURADOS. Most of the reported results are based upon the ICRP30/54 model but one laboratory gives an estimate of the body burden based upon the ICRP 66/67 biokinetic models. (author)
