研究结果表明：散裂产物具有较大的毒性，特别是在加速器驱动的次临界系统（ADS）要求的入射粒子（质子）能量下，产生了一些处于稀土区长寿命的α放射性核素。
It reveals that the toxicity of the spallation products is often on high-rate , especially those alpha emitting rare earths ( RE ) caused by the incident proton under the ADS required energy largely contribute into overall toxicity of spallation targets .
