摘要

用丙烯酸接枝后的聚乙烯薄膜，可用不同的染料进行染色，制成有色聚乙烯薄膜剂量计。这种剂量计对,60,Co γ射线的剂量响应在一定的范围内呈线性。用不同的染料染成的薄膜有不同的剂量范围。研究了辐照时温度、湿度和辐射角度对这些薄膜的响应的影响，吸收剂量测量的精密度，以及这些膜辐照前后的稳定性。结果表明，有色聚乙烯薄膜可以用于,60,Co γ射线辐照工艺中的常规剂量测量。

Abstract

The polyethylene film grafted with acrylic acid then dyed with some dyestuffs and produced dyeing polyethylene dosifilm. The response of ,60,Co γ ray absorbed dose on these films is a linear. The different dose range dependents on different dyestuffs. The effect of temperature, relative humidities and irradiation angle during irradiation on the response and the deviation of measurement for these films are studied. The stability of these films before and after irradiation is studied too. The research results show that dyeing polyethylene dosifilm are suitable used as a routine dosimeter in radiation processing with ,60,Co gamma radiation.
