摘要
60 Co辐照室在增源放射性活度达 3.5 4PBq后 ,用Fricke剂量计、Ag2 Cr2 O7剂量计、K2 Cr2 O7剂量计进行辐照场的剂量学性能测定 ;并以 75 6MC型紫外可见分光光度计测定了30 3nm、35 0nm及 4 40nm峰值处的摩尔吸光系数。结果表明 ,本辐射场的剂量分布较均匀 ,能适应和满足当前辐照加工业的需求。
After supplementing cobalt source 3.54PBq in 60 Co irradiation chamber, the dose field was measured with Fricke dosimeter, Ag 2Cr 2O 7 dosimeter and K 2Cr 2O 7 dosimeter. The molar absorption coefficients at 303 nm, 350 nm and 440 nm peak points was measured too by uv 756 spectrophotomater. The results showed that the dose distribution in the irradiation field was uniform. The demand of radiation processing was met satisfactorily.
