DID YOU KNOW?
Radium was used in the early 1900s for glow-in-the-dark paint on watches — until workers began suffering from radiation poisoning. [2]
KNOW THE RISK
- Ionizing radiation is common at low levels, but high exposure can damage DNA, cause burns, or increase cancer risk. [1][2]
- Medical and dental X-rays, nuclear power facilities, and certain industrial tools are common sources of high-level radiation. [1]
- Exposure may harm bone marrow, gastrointestinal tissues, and the central nervous system. [2]
- Early symptoms can include tingling, itching, or a sunburn-like rash — signs of cellular damage beneath the skin. [2]
MITIGATE THE RISK
1. Minimize Time, Maximize Distance
- When working around a radiation source, limit your exposure time and increase distance to reduce dose. Shielding and time reduction are key controls. [3]
2. Look for Posted Warning Signs
- OSHA requires that radiation areas be clearly marked with trefoil symbols and access restrictions. Always follow posted precautions. [3]
3. Understand PPE Limitations
- Standard PPE will not block ionizing radiation. Specialized shielding (like lead aprons or barriers) is needed in high-exposure areas. [3]
CHEMICAL & RADIATION SAFETY REMINDER
You can’t see, smell, or feel ionizing radiation — but its effects can be severe. Use time, distance, and shielding to protect yourself. When in doubt, stay out of restricted zones unless properly trained and authorized.
