摘要: 手脚表面污染测量仪用于测量辐射工作人员手部和脚部的放射性污染。为方便校准手部探头的表面活度响应,使校准结果更符合实际测量情况,制作了手部模型和90Sr+90Y薄膜放射源,分析研究了人体组织β散射对测量的影响,同时与使用铝衬底源的校准结果进行了比较分析。

Abstract: Hand-foot surface contamination monitors are usually used in nuclear facilitiesfor radiation protection purpose, which measure surface contamination levels onworkers' hands and feet. A hand model and two plastic film sources were made to facilitate the calibration of surface activity response of hand detectors in amonitor of this kind, and give rise to calibration results more in line with actual measurements. The effects of beta backscatter from hand tissue on measurement were investigated. The calibration results with aluminum substrate sources used were employed to perform a comparison in the meantime. Their difference was then analyzed.

Key words: Hand-foot contamination, Surface contamination measurement, Response, Calibration
