摘要
氚是典型的低毒性、放射性元素,侵入人体之后,能够和氢出现同位素交换反应,进而渗透到人体当中,产生生物辐射效应,辐射监测过程中会释放到环境中,对人体产生内照射危害[1-2].在辐射环境监测过程中,标准物质被广泛用于测量仪器的校正、测量方法的评价[3].本文简要介绍了氚的性质,对标准物质的建档、标准物质的保存使用、验证、期间核查、报废等方面以及氚标准物质在辐射环境监测实验室中的管理进行了探究.
Abstract
Tritium is a typical low toxicity and radioactive element.After invading the human body,it can undergo isotope exchange reactions with hydrogen,which can penetrate into the human body and produce biological radiation effects.During radiation monitoring,it will be released into the environment,posing internal radiation hazards to the human body.In the process of radiation environment monitoring,standard materials are widely used for calibration of measuring instruments and evaluation of measurement methods.This article briefly introduces the properties of tritium,explores the establishment of reference materials,their preservation and use,verification,intermediate verification,and disposal,as well as the management of tritium reference materials in radiation environment monitoring laboratories.
