title: Application of ICP-MS for the assessment of thorium excretion in urine.
abstract: A method for rapid and sensitive determination of thorium in urine by inductively coupled plasma mass spectometry (ICP-MS) is described. The method is sufficiently sensitive to detect 1 ng/L 232Th in urine without any sample preparation. The mean urinary 232Th excretion in 23 unexposed subjects was 6.2 +/- 3.3 ng/d.
