摘要

本文报告了用γ谱仪分析技术对土壤、水泥、原煤、矿泉水和岩石等不同类型样品的226Ra-222Rn平衡系数随样品密封时间的跟踪观测。结果表明

它们依样品和样品制备方法不同而无简单规律性。文中提出了样品的前平衡时间和相应的前平衡系数概念

并进而导出了对于226Ra-222Rn平衡系数未知的226Ra-222Rn未平衡样品快速报告226Ra活度的γ谱测量和数据处理方法。文中明确指出:对226Ra-222Rn平衡系数未知的样品快速报告出不至于置疑的可靠检测结果

不可能做到当天收（送）样品当天出检验测试报告;但是

采用本文提出的测量和数据处理方法

对于那些活度不太低的样品来说

在收样后3到7天出检验测试报告是极具可能的

而不至于非要在收（送）样品后一个月左右才能见到检验测试报告

从而大大缩短了等待时间。

Abstract

This paper reports the observed changes for equilibrium factors between 226Ra and 222Rn with sealing time of the samples. The samples include soil

raw coal

mineral water

cement

rock

etc. Especially the conceptions of “pre-equilibrium time” and “pre-equilibrium factor” have been put forward and methods of measuring and processing data have been given which can be used for rapidly reporting activity of 226Ra in samples with unknown equilibrium factor. It is definitely concluded that

using methods given in the paper

a test report will be completed in 3—7 days

instead of one month

after receiving the sample whose activity is not lower than LLD of the spectrometer.
