Key Stage 5
Meaning
ALARA is a principle in radiation safety aimed at minimizing exposure to radiation as much as reasonably possible.
About ALARA
- Balances the benefits of radiation use with the risks.
- Involves implementing safety measures, optimizing procedures, and using protective equipment.
- Encourages continuous improvement in radiation safety practices.
- Based on the principle that any exposure to radiation carries some risk.
- Promotes the use of time, distance, and shielding to reduce radiation exposure.
- Frequently applied in medical, industrial, and nuclear power settings to protect workers and the public.
- Part of regulatory requirements and guidelines set by organizations such as the International Commission on Radiological Protection (ICRP).
Examples
- Use of lead aprons and shields in X-ray imaging.
- Limiting time spent near radioactive sources.
