Contamination

Usually an undesirable situation where radioactive material in an Unsealed Source (open source) state is present in the working environment, or otherwise non-contained. Contamination can either be loose (easily removed) or fixed. Loose contamination is usually of more concern since intakes of radioactive material through Inhalation, Ingestion and Injection may occur.

What's the matter? What's the antimatter? Does it antimatter?
