一、前言用作增殖核燃料的钍属高毒放射性元素,因而对钍作业人员需进行剂量监测。尿钍值可为估算其所受内照射剂量提供基本数据。在健康普查、临床诊断、事故处理、药物促排中均是一项重要的检验指标。目前,测定尿钍首推中子活化分析法最灵敏,但一般实验室皆受条件所限而不可行。本实验建立了在普通实验条件下,快速灵敏地测定作业人员尿钍值的简便方法。尿样勿需
I. INTRODUCTION Thorium, which is used as a proliferation fuel for nuclear fuel, is a highly toxic radioactive element and therefore requires dose monitoring for thorium operators. Urinary thorium value can provide the basic data for estimating the dose of internal exposure. In the health census, clinical diagnosis, accident management, drug promotion is an important test indicators. At present, the determination of urinary thorium devaluation neutron activation analysis most sensitive, but the general laboratory conditions are not feasible. This experiment establishes a simple and quick method to determine the urine thoron value of workers quickly and sensitively under the common experimental conditions. Urine samples do not need
