Radiology and risk: an economist's perspective

Area of Science:

• Radiological Protection and Medical Imaging
• Health Economics and Policy Analysis

Background:

• The International Commission on Radiological Protection (ICRP) concept of detriment is central to radiation protection.
• Radiopharmaceutical investigations involve patient dosimetry and associated risks.
• Decision-making in healthcare policy often requires balancing costs against benefits, including lives saved.

Purpose of the Study:

• To integrate the ICRP's concept of detriment within a cost-benefit analysis framework.
• To explore methods for valuing human life in policy decisions involving risk reduction.
• To demonstrate the practical application of life valuation in mammography for breast cancer screening.

Main Methods:

• Explanation and distinction of cost-benefit analysis from cost-effectiveness analysis.
• Exploration of methodologies for assigning monetary value to human life.
• Application of life valuation principles to a specific case study: mammography screening.

Main Results:

• Cost-benefit analysis provides a practical tool for policy decisions where lives saved are a key benefit.
• Determining who values life and whose risk perception is relevant is crucial for policy implementation.
• Mammography screening serves as a practical example for applying life valuation in risk-benefit assessments.

Conclusions:

• The ICRP's detriment concept can be effectively operationalized through cost-benefit analysis.
• Valuing human life is a necessary, albeit complex, component of evidence-based health policy.
• Practical application of these principles aids in optimizing public health interventions like mammography.
