摘要

本研究采用自主研发

以NaI为探头的低本底γ测量系统

研究了模拟人体血液的NaCl溶液

在不同照射距离、照射时间下经252Cf中子源照射后24Na比活度的变化。结果显示

比活度与照射距离成指数关系衰减

随照射时间增长成线性关系增加。

Abstract

In an accident of neutron radiation

the neutron dose can be estimated by measuring radioactivity of 24Na in blood of the patients.In this work

NaCl solution as simulated blood was irradiated by a 252Cf neutron source

and measured by a low background γ-ray measurement system.The 24Na activity was measured at different source-sample distances for different irradiation hours.The 24Na activity after decay correction decreases exponentially with increasing distance

but increases linearly with irradiation time.
