Abstract

The notion of "a generalized equivalent dose" was introduced in order to use an equivalent dose as a dosimetric criterion for the estimation of acute exposure to densely ionizing radiation. The generalized quality coefficients that were used to quantify a generalized equivalent dose depended on LET, and with gamma/neutron radiation, on neutron energy. Several possible LET functions of the generalized quality coefficients were chosen and mean quality coefficients were transformed, depending on neutron energy, and estimated for actual neutron energy distributions, used in radiobiological experiments, with due regard for the alteration in the neutron spectrum with the body depth.

摘要

引入“广义当量剂量”这一概念是为了将当量剂量用作估算急性密集电离辐射暴露的剂量学标准。用于量化广义当量剂量的广义品质系数取决于传能线密度(LET),对于γ/中子辐射,还取决于中子能量。选择了广义品质系数的几种可能的LET函数,并根据中子能量对平均品质系数进行变换,针对放射生物学实验中使用的实际中子能量分布进行估算,同时适当考虑中子能谱随身体深度的变化。
