摘要:

应用自制的能量50~60 keV的准单色X射线机替代241Am低能光子源(1.11×109 Bq)应用于BS-03测厚仪进行测厚研究,分别测试了BS-03测厚仪输出电流范围,测试X射线在钢板、铝板、有机玻璃的衰减规律以及准单色X射线机稳定性,结果表明,准单色X射线机可以替代241Am放射源用于BS-03测厚仪。

Abstract:

In the research of BS-03 thickness detector, a self-designed quasi-monochromatic (50-60 keV) X-ray machine was studied as a substitution to Am-241 low energy photon source(1.11×109 Bq)The range of output current, the attenuation of X rays through the steel plate, the aluminum plate, and the organic glass plate and stability of quasi-monochromatic X-ray machine was tested. The result showed that quasi-monochromatic X-ray machine could be an applicable replacement of Am-241 radioactive source.

Key words: quasi-monochromatic, X-ray machine, replace, radioactive source
