中文摘要：

用LCS＋CBURN程序计算在线同位素分离器靶-源中铅、钨、铜、铝、石墨靶材料以及结构材料水、不锈钢在100 MeV、200μA强流质子束照射下所产生的放射性核素活度以及γ射线强度随时间的变化,以便为靶的设计、更换以及后期处理提供一定的设计依据。所选靶材料在照射后会产生长寿命放射性核素氚,其中,铅靶材料中还会产生^131I。

英文摘要：

The variation of the induced radioactivity and gamma ray intensity with time for the irradiated target materials of on-line isotope separator target-source system by a proton beam with energy of 100 MeV and intensity 200 μA were calculated by LCS＋CBURN code.This work will provide a reference to the design,exchange and disposal of target.The tritium was produced after irradiation by proton beams for all target materials,especially there is ^131I in lead target material.
