NF-86、NF-87与FWT-60三种辐射变色染料尼龙薄膜剂量计性能的比较研究

A comparative study of radiochromic nylon film dosimeters NF-86,NF-87 and FWT-60

NF-86和NF-87两种剂量计均是以尼龙为基质材料,分别以六羟乙基付品红氰化物和付品红氰化物为辐射变色染料的薄膜剂量计。本文给出这两种剂量计与国外同类产品——美国远西公司的FWT-60辐射变色尼龙薄膜剂量计主要剂量学性能比较研究的结果。结果表明NF-86、NF-87剂量计的性能已接近和达到美国FWT-60剂量计的水平,能够为国内辐射加工中γ剂量测量(10~3—10~5Gy)提供一种简便快速而又可靠的监测手段。

The newly developed Model NF-86 and NF-87 radicchromic nylon film dosimeters were manufactured from the host of nylon, with HPR-CN and PR-CN as radiochromic dye respectively. In this paper the results of the comparative study of NF-86, NF-87 with FWT-60 (a U. S. A. product) dosimeters were described, which show that the main dosimetric characteristics of NF-86, NF-87 and FWT-60 dosimeters were almost the same. The NF-86 and NF-87 can therefore serve as simple, quick and reliable means for routine dose monitoring (ranging 103-105 Gy) in radiation processing.
