摘要

本文概述和比较了六羟乙基副品红氰化物（HPR-CN），六羟丙基副品红氰化物（HPPR-CN），和副品红氰化物（PR-CN）三种辐射变色染料的尼龙薄膜剂量计的制备和剂量特性。它们的剂量测量范围在0.5—200kGy，其优良的环境适应性使它在实际的常规剂量测量中比聚乙烯醇缩丁醛（PVB）薄膜更为相宜。文中介绍了RCR-86型双波长辐射变色多用读数器和模拟双波长测量法，从而抵消了来自剂量计表面的反射、散射及几何位置不重复所造成的误差。

Abstract

The preparation and dosimetric characteristics of three types of radiochromic nylon film dosimeter

which contain lauco dyes of pararosaniline cyanide (PR-CN)

hexahydro-xyethylpararosaniline cyanide (HPR-CN) and hexahydroxypropylpararosaniline cyanide (HPPR-CN) respectively

are outlined and comparatively studied. With a dose range of 0.5-200kGy

and high environmental stability and durability

nylon film dosimeters are more suitable for practical routine dose measurement than polyvinylbutyral (PVB) matrix film dosimeters.

In order to improve the precision a dual wavelength radiochromic multireader Model RCR-86 and a simulated dual wavelength spectrophotometric method are recommended

which cancel the deviation originated from surface reflection

scatering

geometric positioning etc.
