The 90 Sr 90 Y β source is used to the on line measurement system for irradiation effects. The bremsstrahlung dose of the source is calculated and measured. 对90Sr90Y源半导体辐照效应在线测量系统中所用辐射源与周围物质相互作用所产生的轫致辐射剂量进行了理论计算和实验测量。
The coupled electron-photon transport Monte-Carlo computer code PENELOPE was employed for theoretical calculation of thick-carbon-target bremsstrahlung spectrum. The absolute value of the efficiency calibration was determined from the use of~ ( 241) Am radioactive standard source. 厚碳靶的理论韧致辐射能谱由Monte-Carlo程序PENELOPE计算,并用241Am标准放射源确定出效率刻度曲线的绝对值。
