Study Notes
- Radiation protection in diagnostic radiology includes three types of exposure: medical, occupational, and public.
- Medical exposure is for diagnosis or treatment and includes comforters, volunteers, and individuals.
- Framework of radiological protection includes justification, optimization, and practical measures.
- The decision to adopt a practice involving radiation use is based on benefits and disadvantages, with consideration of resources and potential exposure.
- Justification has three levels: generic, specific procedure and application, and individual patient.
- Optimization is applied at two levels: equipment design and day-to-day practice.
- Optimization does not necessarily mean reducing patient doses and can include simple measures and quality objectives.
- Considerable scope exists for dose reductions in diagnostic radiology through simple, low-cost measures.
- Doses should be "as low as reasonably achievable" while maintaining required image quality objectives.
- Radiological practices should be reviewed from time to time as new information becomes available.
- No radiological examination is justified for insurance purposes without clinical indication, except if it provides useful information on the health of the individual examined or if the examination is requested in consultation with relevant professional bodies.
- Optimization of protection in diagnostic radiology includes reducing patient dose, improving image quality, and reducing resources.
- The IAEA provides training material on radiation protection in diagnostic and interventional radiology.
