MASS ATTENUATION COEFFICIENTS, MASS ENERGY-ABSORPTION COEFFICIENTS AND ABSORBED DOSE CHANGE COEFFICIENTS OF CROP SEEDS

本文测定了9种农作物种子和几种无性繁殖植物材料的元素重量百分组成、组织密度,根据Hubbell给出的不同元素质量减弱系数、质能吸收系数,计算了农作物种子和无性繁殖植物材料的质量减弱系数和质能吸收系数,并根据特定情况下导出的“相应点剂量转换法”数学模型,计算了农作物种子或无性繁殖植物材料的吸收剂量转换系数。

The structure and constituent percentage of element in the seeds of nine kinds of crop and several kinds of vegetative propagation plants have been summed up and calculated. Based on the mass attenuation of dif-ferent energyγ-photon, energy absorption coefficients given by Hubbell, the coefficients of crop seeds and vegetative propagation plants have been computed, and according to the mathematical model of 'the Method of Relative Heat Dose Change' provided in special situation, the relative exposure and dose change coefficients have been listed.
