对所研制的硫酸亚铁剂量计(Fricke剂量计)在~(60)Co的γ-辐射场中进行水中吸收剂量测定。测量重复性好于1%。经过两年多考验,该剂量计仍保持着良好性能。在40—400 Gy剂量量程范围内,总不确定度为±2.1%(95%置信度)。
The absorbed dose of iron in ferrous sulfate dosimeter (Fricke dosimeter) was measured in γ-radiation field of ~ (60) Co. Measurement repeatability better than 1%. After more than two years of testing, the dosimeter still maintains good performance. The total uncertainty was ± 2.1% (95% confidence) over the 40-400 Gy dose range.
