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.
