摘要
使用丙烯酰胺、明胶、交联剂、除氧剂、甲醛和琼脂糖等,在常氧条件下制备出四种不同配比的聚合物凝胶剂量计。根据U型管两端水平液面恒等原理,在32℃和60℃下比对筛选出具有较高熔点的凝胶剂量计,实验结果表明PAGAT加入适量甲醛所得的聚合物凝胶剂量计具有60℃以上的熔点,可以很好抵御环境温度的大幅度变化,并且有很好的剂量线性响应特性。
Four types of polymer gel dosimeter, containing aerylamide, gelatin, BIS, THPC, formaldehyde and agarose, were prepared under normal atmospheric conditions. Aecording to the principle of Utype test tube, we screened out the gel with high melting point at 32℃ and 60℃. It turned out that the PAGAT gel mixed with formaldehyde had a melting point over 60℃, which made the gel resist the varied environment temperature to a great extent. And it also had a good liner response with its absorbed dose.
