摘要
应用核素示踪方法研究稀土元素(147Pm,141Ce,147Nd)在动物脏器中的蓄积性,从大脑、眼球、睾丸和骨骼中的蓄积情况,探讨了人们长期摄入低剂量稀土及其天然放射性核素的射线内照射可能产生的生物效应。
The distribution, accumulation in the body of animals were studied using radioisotope tracer (147Pm, 141Ce, 147Nd) method. From the accumulation of these elements in brain, eyes, testes and skeleton, the biological effects of low dosage RE for long attract and internal radiation of natural radioactivity in the RE were investigated.
