Elektra, you may have worked at Hanford, but you are showing yourself to be damned ignorant of what radiation is. Alpha is emitted by Plutonium in massive amounts. One speck of Plutonium in your lungs, and you are going to develop cancer. Plutonium is one of the elements created in the use of Uranium to fuel the commercial reactors.
Plutonium
Over one third of the energy produced in most nuclear power plants comes from plutonium. It is created in the reactor as a by-product.
Plutonium has occurred naturally, but except for trace quantities it is not now found in the Earth's crust.
There are several tonnes of plutonium in our biosphere, a legacy of atmospheric weapons testing in the 1950s and 1960s.
In practical terms, there are two different kinds of plutonium to be considered: reactor-grade and weapons-grade. The first is recovered as a by-product of typical used fuel from a nuclear reactor, after the fuel has been irradiated ('burned') for about three years. The second is made specially for the military purpose, and is recovered from uranium fuel that has been irradiated for only 2-3 months in a plutonium production reactor. The two kinds differ in their isotopic composition but must both be regarded as a potential proliferation risk, and managed accordingly.
Plutonium, both that routinely made in power reactors and that from dismantled nuclear weapons, is a valuable energy source when integrated into the nuclear fuel cycle. In a conventional nuclear reactor, one kilogram of Pu-239 can produce sufficient heat to generate nearly 10 million kilowatt-hours of electricity.
