[Risk assessment in diagnostic radiation dosimetry]

Area of Science:

• Radiological Protection
• Diagnostic Radiology
• Radiobiology

Context:

• Current regulations for radiological protection in diagnostic radiology are based on theoretical assumptions, not empirical data on low-dose harm.
• There is a lack of demonstrated bio-negative effects from low radiation doses in individuals or epidemiological studies.

Purpose:

• To highlight the need for a benefit-risk analysis in all radiodiagnostic and nuclear medicine procedures.
• To emphasize the necessity of understanding radiobiological principles and current assumptions for optimizing radiological protection.

Summary:

• Regulation of radiological protection in diagnostic radiology is predominantly based on theoretical assumptions rather than quantitative data of harmful effects.
• Bio-negative effects of low radiation doses have not been substantiated by individual or epidemiological data.
• A benefit-risk analysis is crucial for every radiodiagnostic and nuclear medicine procedure.

Impact:

• Informing the optimization of radiological protection strategies in diagnostic imaging.
• Guiding future research towards acquiring quantitative data on low-dose radiation effects.
• Enhancing the scientific basis for radiation safety protocols in medical imaging.
