  1.  @MarkRose1337  Quick search suggests that you get 0.003 mSv/h of extra radiation at 30000 ft and yearly limit for nuclear workers is 20 mSv. Getting over the nuclear worker safety limit would require more than about 6000 hours per year above 30000 ft assuming normal background conditions on ground. I'd assume most airline workers do less hours per year. To put these numbers into perspective, yearly natural background radiation here in Finland is about 3.2 mSv per year. In the end, no amount of radiation is truly safe but the nuclear worker limit of 20 mSv is considered safe in practice.

  2.  @MarkRose1337  Thanks for the reference. I quickly went through the paper and even though I might usually consider studies based on self-reported surveys not that trustworthy, this had big enough sample size that it probably doesn't cause problems. It seems that there definitely is higher amount of cancer for the airline crew. However, I'm not sure if that's correlation or causality. According to the Table 1, the 95% CI range goes from below 1 to above zero SPR (multiplier for the probablity of getting cancer) for nearly all findings. Biggest exceptions are skin-related issues and breast cancer. The breast cancer is indeed an interesting finding! It looks like the breast cancer is 1.5x more probable for airplane crew. But I disagree about skin-related issues. Cosmic background radition (which is the only cause for the increased radiation in airplanes) doesn't stop at skin like alpha or beta radiation so it should cause any type of cancer with similar probability. I think it's much more plausible explanation that working within airline allows accessing locations with lots of sunshine (and UV radiation) much more often than general population. As a result, majority of the skin-related issues are probably caused by UV exposure instead. To the credit of the authors, they did mention some of the above limitations in the paper.
