研究分析了加速器驱动洁净核能系统(ADS)中钨靶受质子照射一段时间后在水体中产生的辐射剂量分布和辐射剂量随存放时间的变化规律.研究结果表明:钨靶的散裂产物中长寿命放射性核素较少;辐射主要分布在沿靶半径方向的10～30 cm和距靶两底面的15 cm范围内;靶中的辐射剂量率10年后趋于稳定.

The dose distribution and dose rate over time of Tungsten target in water irradiated by proton for period of time in ADS are analyzed. Results show that the long - life radiation nuclei in Tungsten spallation target is less. The radiation is mostly distributed in the area of 10 - 30 cm along the radius and 15 cm underside of target. The dose rate of Tungst...
