Containment: Radioactive materials
Control Measure Knowledge
This control measure should be read in conjunction with Containment of polluting materials
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
