摘　　要：对辐射致色薄膜剂量计（PVG）的辐照响应过程进行了研究，发现其剂量响应曲线上有一极大点考查了隐色孔雀绿（LMG）的极大转化率Cext与隐色孔雀绿（LMG）和有机卤代物（RX）量含量的关系，进而讨论了PVG膜剂量计线性响应范围的上限与膜中LMG量含量的关系．在该体系中当LMG量含量在20～11μmolg-1范围内时，其线性响应范围的上限估计在140～110kGy范围内．The irradiation response of radiochromic film dosimeter (PVG) is investigated. It is found that there is an extreme point in its dose response curve. The relations between the extreme percent convereion (Cext) of leuco malachite green (LMG) and the content of LMG and halogented organic compound (RX) are studied. And the relatinn between upper limit of linear response range of PVG film dosimeter and its content of LMG is discussed. The upperlimit of linear response range of PVG film dosimeter is in the range of 140 ~ 110kGy, if the content of LMG is in the range of 20 ~ 100μmol. g-1.
