• Protection from Radiation Hazards - Time » The less time spent near the source, the
smaller the dose
- Distance » Maximizing distance minimizes dose
- Shielding » Intervening material can block radiation

Emergency Procedures
• Secure a Safe Area - Minimum safe distance of 5 meters
• Restrict Safe Area - Easily observable barrier with warning signs - If possible, do not leave the area unattended
• Contact Supervisor - CNSC Interface
• Call Appropriate Emergency Personnel - Inform them of presence of gauges
Emergency Procedures
• Re-admittance to area requires - Dose rate monitoring - Contamination monitoring
• The CNSC must be notified: - Within 48 hours of the incident - Within 24 hours if material is lost or
stolen
Safety Overview
Close the shutter when:
- When unit is down for extended periods
- performing maintenance on line or
detector
- performing leak tests
Summary
When working with radioactive material: - Consider your time around material
- Remember to stay at a safe working distance - DO NOT attempt to bypass any shielding - Wear any required protective clothing - Wear any required TLD or DRD monitors in the most appropriate place - Only work in designated areas - Clean work area after use - Keep an inventory of all radioisotopes - Know what to do in an emergency
