摘要
钚的内照射剂量可通过生物样本的测定结果和摄入滞留或排泄函数修正的办法来确定。本文从原理、方法学、在剂量重建中的应用几方面综述了尿钚分析方法。尿钚分析方法主要包括α谱仪分析方法、裂变径迹分析方法,电感耦合等离子体、热电离、加速器等质谱分析方法,每种方法优势不同。本文可为基于钚内照射剂量重建尿钚分析方法的选择提供参考。
The internal exposure dose of plutonium can be determined by the detection of biological samples and the correction of retention or excretion fraction with time after intake.This paper reviewed the analytical methods of plutonium in urine from the aspects of principle,methodology and application in dose reconstruction.The plutonium analysis methods mainly include alpha spectrometry,fission-track analysis,several types of mass spectrometry,such as inductively coupled plasma mass spectrometry,thermal ionization mass spectrometry,accelerator and other mass spectrometry.The advantages of each method are different.This paper can provide reference for the selection of urinary plutonium analysis methods based on the internal dose reconstruction.
