Summary

The U.S. Federal Aviation Administration (FAA) now recognizes flight crews as workers exposed to occupational radiation. The FAA developed a tool to estimate cosmic-ray exposure and provides risk information to flight personnel.

Area of Science:

  • Aviation Safety
  • Occupational Health
  • Radiation Biology

Background:

  • Flight crew members are recognized as occupationally exposed to radiation.
  • Previous assessments by the FAA suggested minimal regulatory involvement was needed for in-flight radiation exposure.
  • There has been a shift in regulatory perspective regarding flight crew radiation exposure.

Purpose of the Study:

  • To inform flight crew members about their occupational radiation risks.
  • To provide tools for assessing cosmic-ray exposure from flights.
  • To encourage educational programs for flight crews on radiation risks.

Main Methods:

  • Development of a computer program by the FAA to estimate cosmic-ray exposures.
  • Publication of informational documents detailing statistical radiation risks.
  • Issuance of an advisory to air carriers for employee education programs.

Main Results:

  • The FAA now actively provides resources for flight crew radiation risk assessment.
  • Informational materials and advisories have been disseminated to crew members and air carriers.
  • A proactive approach to managing in-flight radiation exposure has been adopted.

Conclusions:

  • The FAA's current stance emphasizes worker protection and education regarding in-flight radiation.
  • These initiatives represent a significant shift towards acknowledging and managing occupational radiation exposure for flight crews.
  • The developed tools and advisories aim to empower flight crews with knowledge of their radiation exposure risks.
