美国原子能委员会汉福特工厂的大量低水平放射性废物来自8个生产堆的带有微量杂质冷却水(每天用几百万加仑)。废水尖倾入河流以前,贮藏在水槽内,以便使绝大部分的放射性衰变消失。倾入河流前还需将剩余放射性废物稀释,以保持河水 Much of the low-level radioactive waste at the Hanford plant at the Atomic Energy Commission comes from eight production heaps of cooling water (millions of gallons a day) with trace impurities. The waste water is stored in the sink before it is poured into the river so that most of the radioactive decay will disappear. The remaining radioactive waste needs to be diluted to preserve the river before it can be poured into the river
