摘要：

Urinary excretion of Th-232 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 daily Th-232 excretion was 47+/-26 mu Bq.d(-1) (range 17-121 mu Bq.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.
