Effective Decontamination Methods for Radioactive Objects.

Objects and people exposed to dangerous levels of radiation can be decontaminated by wiping down the contaminated object or washing it with soap and water. Heavily contaminated objects are decontaminated using strong chemicals such as nitric acid and permanganate. If an object can't be decontaminated with water or chemical treatments, it's probably best to put it in the storage silo. Many hazardous radioactive materials take an extremely long time to peter out on their own.
