摘要

建立了低能X射线基准辐射装置。在离辐射源1 m处得到非均匀性<1%的辐射野直径>40 mm,建立了5个CCRI推荐的低能X射线标准辐射质,研究低能X射线衰减规律,测定了半值层和同质系数。该装置的建立为低能X射线空气比释动能量值复现、完成2010年亚太地区APMP.RI(I)-K2国际关键比对、建立低能X射线空气比释动能基准、解决辐射剂量仪表量值溯源奠定了基础。

Abstract

The radiation equipment for air-kerma primary standard in the range of low-energy X-rays is established.The results of experiment show that the diameter of the radiation field is more than 40 mm within 1% non-uniformity.The distance from the source to the reference plane is 1 000 mm.Radiation qualities recommend by CCRI are established.The half value layer(HVL)and the homogeneity coefficient are obtained by measuring the curve of x-rays attenuation.This low-energy X-rays radiation equipment and research results are the important base of establishing primary standard,realization of air-kerma and the APMP key comparison in the range of low-energy X-rays(APMP.RI(I)-K2).
