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)Coγ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)Coγ射线辐照工艺中的常规剂量测量。The polyethylene film grafted with acrylic acid then dyed with somedyestuffs and produced dyeing polyethylene dosifilm. The response of ^(80)Coγ ray ab-sorbed dose on these films is a linear. The different dose range dependents on differentdyestuffs. The effect of temperature, relative humidities and irradiation angle during irr-adiation 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 re-sults show that dyeing polyethylene dosifilm are suitable used as a routine dosimeterin radiation processing with ^(60)Co gamma radiation.
