... herds of deer, elk, moose, and other large mammals in check, as well as keeping these populations strong and genetically viable by preying on the weak and sick.

When in the reactor, the 235U is gradually depleted and gives rise to fission products, generally, cesium (137Cs) and strontium (90Sr). These waste materials are very unstable and have to un ...
