From the FAA, >.02 mSv per hour measured for LA to Tokyo [1] From Wikipedia, .02 mSv for chest x-ray [2] [1] https://www.faa.gov/data_research/research/med_hu

  I'm not sure that banana chart from wikipedia is up-to-date: https://www.radiologyinfo.org/en/info.cfm?pg=safety-xray https://www.radiologyinfo.org/en/info.cfm?pg=safety-xray https://www.health.harvard.edu/cancer/radiation-risk-from-medical-imaging https://www.health.harvard.edu/cancer/radiation-risk-from-me... Most sources seem to put it at 0.1 mSv for a chest x-ray. The FAA link for a Tokyo to LA 9 hour flight would be about 0.0206 mSv, or approximately 2 chest x-rays for the total flight. However the FAA research you linked would put a New York to Seattle flight at a total of 0.112 mSv, whereas this CDC link says a trans-continental flight is only at the order of mangnitude of 0.035 mSv... https://hps.org/publicinformation/ate/faqs/commercialflights.html https://hps.org/publicinformation/ate/faqs/commercialflights... - summarizes more sources that contradict the raw FAA numbers. This FAA calculator also seems to give numbers that agree with the lower radiation levels: http://jag.cami.jccbi.gov/cariresults.asp http://jag.cami.jccbi.gov/cariresults.asp
