处置到自然环境中的放射性废物,经过若干年后,其中一部分还能重新回到人类生活环境中来。因此,在处置放射性废物的同时,必须考虑到被处理的废物可能引起危害的防护问题,这是关系到将来子孙后代的事情。从这一点出发,就要做到:既要利用原子能,又不能给未来的人类社会留下不良的后果。为此,世界各国正在研究开发多种不同的放射性废物处置方式。七十年代,各国对废物埋藏的选址和处置的废物体本身都有严格的规定,象含钚一类的α废物已不允许采用浅层埋藏处置,必须象高放废物一样在深地层处置。其他的中 Radioactive wastes disposed of in the natural environment can, some years later, be returned to humankind. Therefore, while disposing of radioactive waste, we must take into account that the disposal of wastes may cause harm to the protection issue, which is of concern to future generations. Proceeding from this point, it is necessary to make use of both the atomic energy and the unmanageable consequences for the future human society. For this reason, various countries in the world are studying and developing a variety of different radioactive waste disposal methods. In the 1970s, all countries imposed strict rules on the location and disposal of wastes themselves. For example, α-wastes such as plutonium did not allow shallow burial and had to be disposed of in deep formations like high-level waste . Other
