在聚乙烯醇缩丁醛（PVB）薄膜中添加LMG及有机卤代物（RX），研制成功PVG剂量计，并对其性能作了探讨[1]。结果表明，60Coγ射线辐照能引发体系中隐色的LMG氧化生成绿色的孔雀绿（MG+），生成数量与吸收剂量成正比。通过改变基体中LMG或RX的浓度，可以获得不同的线性剂量响应关系（即单位厚度的吸光度差△A／L，mm-1与剂量，kGy之间的关系），对合理控制PVG剂量膜的组成具有指导意义。此外，还初步探讨了该体系的辐射变色机理。
In the polyvinyl butyral (PVB) film added LMG and organic halogen (RX), developed a successful PVG dosimeter, and its properties were discussed [1]. The results show that 60Co γ-ray irradiation can induce the leuco-LMG oxidation in the system to generate green malachite green (MG +), and the generated amount is proportional to the absorbed dose. By varying the concentration of LMG or RX in the matrix, different linear dose-response relationships (ie, the difference in absorbance per unit thickness ΔA / L, the relationship between mm-1 and dose, kGy) can be obtained, Composition is instructive. In addition, the mechanism of radiation discoloration of the system is also discussed preliminarily.
