What should my employer be doing about cosmic radiation?

Air crews exposure to cosmic radiation is regulated by the European Air Navigation Order 2000, and aircraft capable of flying above 49,000 feet must carry an active radiation monitor so that employers know how much cosmic radiation their crew has been exposed to. If annual exposure is below 1 mSv, no controls are required. If annual exposure is above 6 mSv, individual monitoring must be carried out and airlines should adjust rosters to prevent doses above 6 mSv per year. The European Commission also recommends individual monitoring for crew exposed to between 1 mSv and 6 mSv per year.

Employers must keep records for crew exposed to more than 6 mSv per year for at least 30 years or until the crew member is 75, whichever is longer.
