Study Notes
Radiological Protection
- Radiological protection involves wearing dosimeters to measure radiation exposure.
- Dosimeters are worn in three locations:
- Near the eye (third dosimeter)
- Above the lead apron at neck level (second dosimeter)
- Under the lead apron at chest level (main dosimeter)
Radiation Exposure Limits
- The International Commission on Radiological Protection (ICRP) recommends an effective dose limit of 20 mSv per year, averaged over 5 years.
- Equivalent dose limits are:
- 20 mSv for the crystalline lens
- 500 mSv for the skin
- 500 mSv for the hands and feet
Radiation Protection Principles
- The principles of radiological protection include justification, optimization, and dose limitation.
- Justification involves weighing the benefits of a radiological procedure against the risks.
- Optimization involves minimizing radiation exposure while maintaining image quality.
- Dose limitation involves setting dose limits for radiation workers and the general public.
