摘要

本文叙述一个用缓发中子计数法测铀的测量装置，测天然铀的探测极限为0.05ppm，测

235

U的探测极限为0.4ppb；无试剂空白误差；无

平衡问题，没有基体和其它干扰；在样品含天然铀1ppm时，分析结果的误差小于4.3%；分析一个样品的时间约3分钟；可自动分析大量的样品，能及时给出分析结果，样品非破坏。本方法特别适用于大规模地质普查样品的分析。

Abstract

This paper describes a measurement device for determination of the uranium content by delayed neutron counting. The advantages of this device are as follows: (1) high sensitivity

the detections limit for natural uranium and

235

U is 0.05 ppm and 0.4 ppb respectively

(2) no blank error

balance problem and other interferences. (3) high accuracy

for 1 ppm natural uranium

the error of the determination is less than 4.3%. (4) simplicity

the analyzing time for one measurement is three minutes. (5) It can automatically analyse large amount of samples and immediately give its results. (6) samples are nondestructive. It can determine ten to twenty thousand samples per year. This equipment is suitable for determination of large amount of geological explorative samples.
