摘要: 根据吸收剂量与中子注量的关系,采用活化法测量了试管内样品的中子吸收剂量。实验表明,采用具有反应阈的活化箔能较好地监测少量含氢材料中的中子注量,从而确定样品中的中子吸收剂量。

Abstract: Based on the relation between absorbed dose and neutron flux, the absorbed dose of samples was measured in tubes by foil activation technique. The measurement shows that the neutron flux of material contained some hydrogen can be measured well using activition foils with reactivition threashold to determinate the neutron absorbed dose of samples.
