Control measure Containment: Radioactive materials
Control measure knowledge
An unsealed source is a dust, powder or liquid. When released within a building the source can be contained within the confines of the structure. When released outside, weather conditions can significantly affect the dispersal of the material.
The hierarchy of pollution control can be used as framework to identify the most appropriate intervention. Methods for containing unsealed radioactive materials may include:
- Closing or returning to the container
- Switching off ventilation inside a building
- Closing doors and windows
- Covering spillages when they occur outside
- Using booms for containing liquid contaminants
For further information regarding the prevention of environmental contamination see National Operational Guidance: Environmental Protection
Strategic actions
Provide procedures and support arrangements regarding the hazards that may be encountered and actions to take to prevent unsealed radioactive sources being dispersed into the environment
Provide containment equipment to prevent the dispersal of radioactive materials
Tactical actions
Attempt to contain the release of any radioactive materials as close to the source as possible
Gain specialist advice regarding the mitigation of a release of radiation sources
Consider deploying environmental protection equipment to prevent contamination from entering a water course
Monitor elevated background radiation down-wind of the incident
Liaise with specialist agencies to arrange for all radioactive contaminants to be managed on scene
