| In 2012, measurements of an extreme solar flare that missed earth by 7 days, along with analysis that showed such an event had a 12% probability of occurrence per decade led the US and UK science and technology advisors to recommend a course of action should such an event occur. Unlike the US, carriers in the EU and UK are regulated, and the doses that would have been received exceeded allowable limits. There are no radiation dose limits for US aircrew and passengers. This PEP will summarize the conclusions of those meetings and address both routine and extreme events from radiation that occur in flight. The PEP will also address methods that are being considered to control that radiation routinely and during space weather events. Recent efforts by the ISO to develop standards for measurement of radiation in flight will also be summarized. |
