Radioactive contamination or radiological contamination is the contamination of the environment with radioactive materials, where these materials are not present. Many radioactive substances have very long half lives; this means that if they are present in the envioroment, they can be dangerous for a very long time. Many nuclear power plants produce such substances; usually they are processed to radioactive waste. There is little danger that comes from radioactive waste,if it is stored safely.
