55—150keV过滤X辐射源

Filtered X-ray sources with energy 55-150 keV

本文介绍了用过滤法得到的一组能谱分布较窄的X辐射源。适用于55—150keV能区辐射监测仪表的刻度。配合K荧光X射线源和^(61)Cr、^(137)Cs、^(60)Co等γ参考源,可用于剂量仪能量响应的细致研究。

This paper presents a method to obtain, by using filtration, an X-radiation source-with a group of narrower energy-spectral distributicn ranging fron 55 to 150keV. The radiation source can be vsed to calibrate the instruments for radiation detection. Together with a K-fluorescent X-ray source and reference γ-ray sources such as 51Cr, 137Cs, 60Co etc., it is a useful tool for detailed studies of the energy response of some dosimeters.
