Radioactive waste is waste material containing radioactive chemical elements that does not have a practical purpose. It is sometimes the product of a nuclear process, such as nuclear fission. The majority of radioactive waste is "low level waste", meaning it has low levels of radioactivity per mass or volume. This type of waste often consists of items such as used protective clothing, which is only slightly contaminated.

Sources of waste

---

NORM (naturally occurring radioactive material)

Processing of substances containing natural radioactivity, this is often known as NORM. Much of this waste is alpha particles emitting matter from the decay chains of uranium and thorium.

Coal

Coal contains a small amount of radioactive nuclides, such as uranium and thorium, but it is less than the average concentration of those elements in the Earth's crust. They become more concentrated in the fly ash because they do not burn well However, the radioactivity of fly ash is still very low. It is about the same as black shale and is less than phosphate rocks, but is more of a concern because a small amount of the fly ash ends up in the atmosphere where it can be inhaled.[http://geology.cr.usgs.gov/energy/factshts/163-97/FS-163-97.html.
