1942年12月,人类与自然界的关系经历了一次深刻的变化。一位美籍意裔物理学家恩·费米在芝加哥一间地下室里收集了足够的铀后,成功地进行了核裂变链式反应,原子核分裂后释放出结合物质的内在能量。费米的发现几乎立即转移到制造武器方面,同时也产生了对廉价能源的期望。但是,未能预料它所带来的放射性废料将会长期危害人类的健康,成为现代科技造成的一大有害遗产。目前,世界上已有8万余吨辐照燃料和数量更多的其它核废料,若靠其自然衰变来减少
In December 1942, the relationship between man and nature experienced a profound change. After an American-American physicist, N. Fermi, collected enough uranium in a basement in Chicago, he successfully carried out a nuclear fission chain reaction. After the nucleus splits, it releases the intrinsic energy of the binding substance. Fermi’s discovery was transferred almost immediately to the manufacture of weapons, but at the same time it also produced expectations for cheap energy. However, it has not been expected that the radioactive waste it brings will endanger the health of humans for a long time, and it has become a major harmful heritage created by modern science and technology. At present, there are more than 80,000 tons of irradiated fuel and a greater number of other nuclear wastes in the world, which are reduced by natural decay.
