RADIATION PROTECTION IN CANADA. VII. SETTING STANDARDS FOR RADIATION PROTECTION

Area of Science:

• Radiological Protection
• Risk Assessment
• Radiation Biology

Background:

• Current International Commission on Radiological Protection (ICRP) recommendations aim to limit radiation dose to acceptable risk levels.
• Defining 'unacceptable risk' for individuals and populations is a fundamental challenge in radiation protection.

Purpose of the Study:

• To explore the complexities of defining acceptable risk levels for radiation exposure.
• To investigate methods for balancing the benefits of practices involving radiation with their associated risks.

Main Methods:

• Qualitative analysis of ICRP recommendations.
• Comparative risk assessment by juxtaposing radiation risks with other societal risks.
• Conceptual framework for benefit-risk analysis.

Main Results:

• Estimating radiation risks remains challenging, with current assessments being very approximate.
• Societal tolerance for other risks provides a benchmark for evaluating radiation risks.
• Quantitative assessment of both benefits and risks is crucial for decision-making.

Conclusions:

• Establishing acceptable radiation risk requires a societal consensus on risk tolerance.
• A framework for quantitatively assessing and balancing benefits and risks is needed.
• The process of determining and implementing this balance requires careful consideration of who makes these decisions.
