Abstract

Urinary excretion of232Th was assessed, in occupationally non-exposed persons by means of inductively coupled plasma-mass spectrometry (ICP-MS). Measurements were performed in 55 healthy subjects. Mean daily232Th excretion was 47±26 μBq·d−1 (range 17–121 μBq·d−1). Results obtained showed no statistically significant correlation with age and no differences were found between males and females. The impact on the assessment of intakes by workers is discussed.
