Radioactive Material Container Types
Excepted Industrial Type A Type B Type C
Radioactive Material Containers: Excepted
Used to transport materials with extremely low levels of radioactivity that presents no risk to the public or environment. Ex. Smoke Detectors.
Radioactive Material Containers: Industrial
- Materials that present limited hazards
- Slightly contaminated clothing; lab samples
Radioactive Material Containers: Type A
- Designed to survive normal transport, handling, and minor accidents.
- Contains limited quantities of radioactive material.
- Cardboard boxes, wooden crates, or drums
Radioactive Material Containers: Type B
- Designed to survive severe accidents.
- Contains large quantities or radioactive material
- Metal drum, or huge, massive shielded transport container
Radioactive Material Containers: Type C
-Similar to Type B but supported for Aircraft transportation.
