Occupational Radiation Dose Limits

Source:  Occupational Radiation Dose Limits    Tag:  radiation exposure limits


Facts:
  • International Commission on Radiological Protection (ICRP) issues periodic recommendations on radiation protection. The Commission was founded in 1928.
  • ICRP's latest publication was Publication 103 (2007)
  • ICRP effective dose limit for radiation worker (occupational dose limit) = 20 mSv per year when averaged over 5 years; any year limit to 50 mSv
  • The most highly exposed workers are unlikely to receive regular annual effective doses more than 5 mSv
  • Radiation workers should be monitored using personal dosimeter (film badges, TLDs)
  • In emergency situations, occupational exposure can exceed these dose limits if lifesaving actions are involved. Older workers with low lifetime accumulated effective doses should volunteer for emergencies.
