本文介绍用国产 IRM81T-TE1型流气式组织等效电离室和低中子灵敏度的能量补偿 G-M 计数管测定快堆裂变中子和γ射线的组织比释动能率,并用美国远西公司(FWT)1C-17A 型组织等效电离室进行了对比测量,两种电离室测量结果符合很好。
In this paper, the tissue specific kerma rate of fast fission neutron and γ-ray in fast reactors was measured by using the domestic energy IRM81T-TE1 flow-plasma equivalent ionization chamber and the energy-compensated GM counter tube with low neutron sensitivity. 1C-17A tissue equivalent ionization chamber was measured contrast, the two ionization chamber measurements in good agreement.
