Collectively, airline crews are classified as the highest-exposed radiation workers in the US. The two main sources of radiation are “cosmic” (from other stars) and “solar” (from our sun). Exposure to these forms of radiation is not much of an issue on the surface of the earth because the atmosphere serves as a protective layer. But inflight, you have less of that protective layer above you, so your exposure to the radiation is higher. In Europe, airlines must monitor crews’ radiation doses and ensure protections for female crews who choose to report their pregnancy. But in the US, there are no rules to protect crews from over-exposure. For that reason, it is important to educate yourself on inflight radiation basics, especially as they relate to pregnancy. To that end, check out this page and also AFA’s reproductive health webpage. One key message is if you are pregnant, check for solar storms before you fly. Also, we recommend that all crewmembers check out the second edition of “The Invisible Passenger: Radiation Risks for Those Who Fly.” It’s very readable and packed with information - essential reading for crews!

A future app may enable crews and passengers to monitor their inflight radiation dose in real time, based on detailed data collected during 258 high-latitude flights…
raised over backscatter (X-ray) security scanners: When you walk through a backscatter security scanner, it feels like you
are walking between two tall freezers, not to be confused with a millimeter
wave unit in which you stand in a glass booth and are not exposed to X-rays.
There are conflicting reports over whether you should be concerned about the
radiation dose delivered by the backscatter security scanners being installed
at a growing number of airports, especially if you are pregnant, trying to get
pregnant, over 65 or traveling with children. The
Cancer risk for flight attendants: Read AFA's summary of cancer research, last updated in January 2007. The majority of studies found an increase in breast cancer risk for female flight attendants and malignant melanoma for all flight attendants. Some studies note increased risk of cancers of the prostate, brain, and bone. Read about the importance of screening tests to detect any cancer early. For more information, see the Komen Breast Cancer Site, the American Cancer Society, and the National Cancer Institute.

If the green line is above "10 to the zero" on the left side of the graph, it is recommended that pregnant women postpone travel. To help you interpret the graph that you see on your computer screen, here is an example of a graph with no Solar Particle Event (SPE) and here is one with a SPE of health significance. The NOAA Space Weather Prediction Center will also notify you of these solar events for free by email. This is especially important information if you are pregnant. Register as a user, then click on "aviation", "subscribe", "solar radiation events", and then check the following five boxes: (1) WARNING: proton event 10 MeV > 10 PFU expected; (2) ALERT: proton event 10 MeV, exceeded 100 PFU; (3) ALERT: proton event 10 MeV, exceeded 1,000 PFU; (4) ALERT: proton event 10 MeV, exceeded 10,000 PFU; and (5) ALERT: proton event 10 MeV, exceeded 100,000 PFU
