What does the radiation symbol represent?
The presence of this symbol (a magenta or black propeller on a yellow background) on a sign denotes the need for caution to avoid contamination with or undue exposure to atomic radiation. The wording on the sign varies with the level of potential radiation in the area.
What are the 9 hazard symbols?

- Explosive (Symbol: exploding bomb)
- Flammable (Symbol: flame)
- Oxidising (Symbol: flame over circle)
- Corrosive (Symbol: corrosion)
- Acute toxicity (Symbol: skull and crossbones)

What can ionizing radiation cause?
When ionizing radiation interacts with cells, it can cause damage to the cells and genetic material (i.e., deoxyribonucleic acid, or DNA). If not properly repaired, this damage can result in the death of the cell or potentially harmful changes in the DNA (i.e., mutations).
Which color is used for radiation hazard?
Purple – used for radiation hazards. It may contain a combination of purple and yellow.
Where is the radiation symbol found?
All areas and equipment in which radioactive material is stored and used may be posted (labeled) with a sign reading Caution – Radioactive Material that includes the conventional three-blade radiation symbol (trefoil). The blades of the symbol must be magenta, black or purple on a yellow background.
What is a nuclear symbol?

Which is a warning sign of ionizing radiation?
The sign is commonly referred to as a radioactivity warning sign, but it is actually a warning sign of ionizing radiation. Ionizing radiation is a much broader category than radioactivity alone, as many non-radioactive sources also emit potentially dangerous levels of ionizing radiation.
