If ya still think they care...
As the meta-analysis from 2006 suggests, airlines should monitor radiation dose and educate crews of the risks involved. Airlines operating in the European Union are required to keep their crew’s annual effective dose under 6 mSv, airlines in Japan try to keep their crew’s exposure under 5 mSv, the Nuclear Radiation Commission require that employees are educated about the health effects of radiation, and health care professionals are recommended to wear dosimeter badges if they are at risk for exposures greater than 5 mSv (Bushberg, 2009).
A European directive on in-flight radiation, which took effect in May 2000, requires airlines to track radiation dosages received by air crew members and to inform them when they breach the level of one millisievert. The dose of in-flight radiation for each transpolar flight between New York and Hong Kong could reach 0.10 millisievert, a standard measure of radiation exposure, even without additional radiation from a solar flare, according to calculations made by Ms. Waters using the U.S. Federal Aviation Administration's CARI-6 computer program.
According to Ms. Water's calculations, a passenger taking no other flights than one round trip on the route every other month could surpass the maximum dosage guideline of one millisievert per year set for the general public by the EU and the Radiological Protection agency.
Calculating separately and independently, Mr. McAulay and Mr. Barish affirmed that radiation from five round-trip flights could surpass the threshold of one millisievert.
They know this and yet........
