摘要

本文讨论了安瓿型Fricke剂量计及其在实用中的影响因素，给出的摩尔消光系数（

）值为2166.7L • mol

-1

·cm

-1

，相应的转换因子（

）值为280.7Gy/∆Abs。对安瓿的预处理和封装技术及剂计量的制作工艺进行了标准化，测量的精密度有效地控制在±1.0%以内（平均值相对标准偏差，95%置信度），总不确定度在±2.5%以内。

Abstract

The ampoule-type Fricke dosimeter and factors that affect its uses were discussed in this paper. The molar extinction coefficient for Fe

at 302 nm was determined to be 2166.7 1/mol·cm (25℃) and the conversion factor for absorbence-absorbed lose was obtained to be 280.7Gy/∆Abs. The technique of pretreatment

sealing of glass ampoule

and prepartion of Fricke dosimeter were standardized

so that the precision of measured valuse has been effectively controlled within ±1.0% (relative standard deviation of an average value at 95% confidence level)

and overall uncertainty within ±2.5%.
