Store in containers surrounded by commercially available lead shielding. Store in containers surrounded by commercially available lead shielding. Because internal doses are generally more hazardous and more difficult to detect and quantitate than external doses, significant emphasis is placed upon prevention. Internal radiation exposures are prevented and limited through the implementation of sound radiological work practices to control and minimize radioactive contamination. Radioactive contamination is actual physical material that typically cannot be seen, but can be transferred from one surface to another through contact.
Controls are necessary to ensure the protection of personnel, facilities, and the environment.
Radioactive contamination can be waterborne, airborne, or deposited directly on surfaces. It also can be easily spread to other surfaces through contact. Areas with nonremovable radioactive contamination generally will be controlled on the basis of the radiation levels produced by the contamination. Contamination Control Requirements 1. Though not required, the wear of two pairs of gloves will provide additional protection.
