Area of Science:

  • Medical Physics
  • Radiological Protection
  • Occupational Health

Background:

  • Operational radiology involves potential radiation exposure for healthcare workers.
  • Accurate dosimetry is crucial for assessing and managing radiation risks.
  • Monitoring dose rates on the body surface aids in evaluating occupational exposure.

Purpose of the Study:

  • To assess the average annual effective dose equivalent for workers in operational radiology.
  • To determine dose equivalents in specific organs like eye lenses and hands.
  • To evaluate radiation exposure levels across various radiological procedures.

Main Methods:

  • Dose-rate measurements were conducted on the body surface of workers.
  • Measurements were performed in 20 hospitals during X-radiation procedures.
  • Data collected allowed for the calculation of effective dose equivalent and organ-specific dose equivalents.

Main Results:

  • Annual effective dose equivalent ranged from 0.1 to 45 mSv, with most below 5 mSv.
  • Eye lens dose equivalents varied from 0.01 to 70 mSv, with one exceptional case at 1.9 Sv/year due to improper procedures.
  • Hand dose equivalents ranged from 0.5 to 140 mSv.

Conclusions:

  • Most workers in operational radiology receive acceptable radiation doses.
  • Exceptional cases of high eye lens dose highlight the importance of appropriate operating procedures.
  • Regular monitoring of occupational radiation exposure is essential for worker safety.
