叙述用双剂量计法较准确地测定了原子能研究院(d+T)中子场的中子和γ辐射在自由空气中的组织比释动能K_N和K_G,其中K_N的总不确定度为4.37％,并与用伴随粒子法确定的中子注量通过换算得到的组织比释动能比对,两者相差小于1.0％。此装置参加了由国际 计量局组织的国际比对,并给出了比对结果。
The bi-kinetic energy K_N and K_G of the neutron and γ radiation in the free-air of the (d + T) neutron field of the atomic energy institute (d + T) are accurately measured by the dual-dosimeter method. The total uncertainty of K_N is 4.37 %, And compared with the kinetic energy of the tissue obtained by the conversion of the neutron fluence determined by the accompanying particle method, the difference between the two is less than 1.0%. This device participates in international comparisons organized by the International Bureau of Metrology and gives the results of the comparison.
