中文摘要：

本实验室分别选用无水乙醇和丙酮溶液为溶剂制成两种类型的辐射变色膜，并对这两种辐射变色膜进行了^60Coγ射线与紫外线辐照，研究不同溶剂对辐射变色膜吸收剂量的影响。实验发现，^60Coγ射线与紫外线辐照后，使用丙酮作溶剂的辐射变色膜变色效果比无水乙醇的更加明显。在相同的辐照剂量下，使用丙酮作为溶剂的变色膜比用无水乙醇的光谱吸收峰（680nm）值平均高65．5％。7射线辐照时，用丙酮作为溶剂的辐射变色膜变色的辐照剂量下限为0．5Gy，而用无水乙醇做为溶剂的为1Oy；紫外辐照时，用丙酮为溶剂的辐射变色膜吸收峰处吸收剂量的线性响应区间为0～6×100μJ／cm^2，而用无水乙醇做为溶剂的为0～36×100μJ／cm^2。

英文摘要：

Anhydrous alcohol and acetone solution are chosen by our laboratory as solvent for the preparation of the two types of radiochromic films, which are irradiated by 60Co γ rays and ultraviolet irradiation, to study dose effect of radiochromic films with different solvents. Experiments have found that the radiochromic films which contain acetone have more obviously color change than the other type when irradiated by 60 Co 7 rays and ultra- violet irradiation. Under same radiation doses, the absorption peaks of the radiochromic films which contain acetone are averagely 65.5% higher than the other type. When irradi- ated by T rays, the lowest doses of discoloration are 1 Gy and 0.5 Gy for the two types of radiochromic films respectively; when irradiated by ultraviolet, the linear response interval are 0-36 × 100 μJ/cm2 and 0-6 × 100 μJ/cm2 for two types of radiochromic films respec- tively.
