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.
描述了一种通过电感耦合等离子体质谱法（ICP-MS）快速灵敏测定尿液中钍的方法。该方法灵敏度足以检测尿液中1 ng/L的232Th，无需任何样品前处理。23名未接触者的尿232Th平均排泄量为6.2±3.3 ng/d。
