If you want to go with the 5 mSv limit, and a chest x-ray is 20 μSv, that's still 833 chest x-rays per year before hitting your annual quota.

- not_a_moth 7y agoSorry your math adds up to 250 not 833 x-rays. Importantly - each year simple, normal living exposes you to 3.5 mSv (see the same chart), so you only get 1.5 mSv to "allocate" to other exposures. In other words you only get 75 chest x-rays per year. By FAA rates of exposure on trans-pacific flights, you should take max 5-6 of those legs per year.
