【摘要】 高能电子直线加速器隧道内的灰尘会通过光核反应、中子核反应而被活化。灰尘活化产生的放射性核素可能引起检修工作人员的内照射。本文简要介绍中国科技大学国家同步辐射实验室 2 0 0MeV电子直线加速器隧道内不同地点灰尘的活化现状 ,并提出相应的防护建议更多还原

【Abstract】 The dust in the high-energy electron linac tunnel may be activated via photonuclear reaction and neutron nuclear reaction. The radioactive nuclides produced by these reactions may cause internal exposure to maintenance workers. This paper introduces the dust activation status at different positions in NSRL 200 MeV linac tunnel and gives some suggestions for radiation protection as well. (更多还原
