摘要
对辐射致色薄膜剂量计（PVG膜剂量计）的辐照响应过程进行了研究，计算出了PVG膜剂量计中孔雀绿（MG+）的辐射化学产额G（MG+）．当膜中组分隐色孔雀绿（LMG）的量含量为80μmol·g(－1)，有机卤代物（RX）与LMG的质量比为0.5时，其G值为0．236μmol·J(－1).考查了膜中组分LMG和RX的量含量变化对G（MG+）的影响．表明PVG膜剂量计中由于LMG和RX的量含量波动而引进的偏差在1％以下，并不妨碍其作为常规剂量计的使用．
The irradiation response of radiochromic film dosimeter(PVG) is investigated,and the radintion chemical yields of malachite green(MG+) in PVG film dosimerter are given. The G value of MG+ is 0.236μmol. J-1 in the content of leuco malachite green(LMG) 80 μmol. g-1 and at the mass ratio of halogenatal organic compound(RX) to LMG 0.5. The influences of the content of LMG and RX on G(MG+) are studied. The deviation of PVG film dosimeter resulted from the content variation of LMG and RX is much less than 1%, which doesn't hamper the use of PVG as a routine dosimeter.
