Вот еще статья с ссылками на научные статье, что риск облучения минимален. Главное много пить воды, шевелить ногами (в этом я с автором вашей ссылки согласна) и не накручивать себя, а главное других (по незнанию)  Available information suggests that noise, vibration, and cosmic radiation present a negligible risk for the occasional pregnant air traveler (6, 7). Both the National Council on Radiation Protection and Measurements and the International Commission on Radiological Protection recommend a maximum annual radiation exposure limit of 1 millisievert (mSv) (100 rem) for members of the general public and 1 mSv over the course of a 40-week pregnancy (7). Even the longest available intercontinental flights will expose passengers to no more than 15% of this limit (7); therefore, it is unlikely that the occasional traveler will exceed current exposure limits during pregnancy. However, aircrew or frequent flyers may exceed these limits. The Federal Aviation Administration and the International Commission on Radiological Protection consider aircrew to be occupationally exposed to ionizing radiation and recommend that they be informed about radiation exposure and health risks (8, 9). A tool to estimate an individual exposure to cosmic radiation from a specific flight is available from the Federal Aviation Administration on its web site (http://jag.cami.jccbi.gov/cariprofile.asp).In the absence of a reasonable expectation for obstetric or medical complications, occasional air travel is safe for pregnant women. Women should check with specific carriers for airline requirements.ReferencesChibber R, Al-Sibai MH, Qahtani N. Adverse outcome of pregnancy following air travel: a myth or a concern?
