本文考虑到影响生物效应的关键因素是吸收剂量,同时根据ICRU的规定和我国采用辐射量单位的现状,计算~(137)Csγ辐射场中农作物的吸收剂量,并换算成国际制吸收剂量单位专名是迫切需要的。为此,测定小麦、水稻六个品种的种子的元素百分含量,计算这些作物种子在~(137)Csγ辐射场中的质能吸收系数和f因子。鉴于适应照射量“过渡”到吸收剂量的需要,换算了30余种作物种子的质能吸收系数及f因子,供我省效应生物学工作者参考。
In this paper, taking into account the biological effects of the key factor is the absorbed dose, and according to the provisions of ICRU and China’s current situation of the use of radiation units, calculate the ~ (137) Csγ radiation field crops absorbed dose, and converted into units of international absorbed dose units Name is urgently needed. For this purpose, the elemental percentages of seeds of six wheat and rice varieties were determined, and the mass absorption coefficient and f factor of these seeds in the ~ (137) Csγ radiation field were calculated. Considering the need of “transition” to absorbed dose, the mass absorption coefficient and f factor of more than 30 kinds of crop seeds are converted, which is useful for reference by our province’s biologists.
