【摘要】 总结了两种体系的辐射变色薄膜紫外辐照规律,并对其特性及反应机理进行了研究。多芳氨基甲烷类化合物体系辐射变色薄膜在能量密度为3mJ/cm~2的紫外线辐照后,其颜色由无色变为绿色,该辐射变色膜的吸光度变化与辐照时间呈线性关系;类丁二炔化合物体系经紫外线辐照后,其颜色由粉红变为蓝色,在辐照仪的最低辐照能量(能量密度:0.2mJ/cm~2,时间:0.1min)下薄膜变色肉眼可分辨,在一定的紫外能量辐照范围内,该辐射变色膜的吸光度变化与辐照能量呈线性关系。当辐照时间超过0.4min时,吸光度不再发生变化,薄膜变色达到饱和。此两种体系的辐射变色薄膜可分别作为高剂量和低剂量响应的紫外变色薄膜剂量计。更多还原

【Abstract】 Summarizes the two kinds of system radiation films to Ultraviolet irradiation,and research its characteristics and reaction mechanism.The multi-aryl amino methane compound radiation films were irradiated by UV irradiation which energy density is 3mJ/cm²,its color changes to Green from colorless,there is a linear relationship between absorbency and the irradiation time of ultraviolet radiation when irradiated by the same energy density;the kind of acetylene-type compounds system radiation films,which color pink turns blue after ultraviolet irradiated,at the lowest radiation energy of irradiating apparatus(energy density:0.2mJ/cm²·s^-1, time:0.1min),the change color can distinguish with eyes,the irradiation time of ultraviolet and absorbency have a linear relationship in a certain range of UV energy radiation.The absorbance is no longer changing when irradiation time exceeds 0.4min,its color reach saturation.The two kinds of system radiochromic film can be useed as UV irradiation dosimeter for the high dose and the low dose measurment separately.更多还原
