Why oh why would a SCIENCE outfit like NASA report radiation exposure in “chest xrays”? Why not Sieverts or milliRems? Then the concerned reader could look up the relative risks.

“Chest Xray” dose depends on the machine, what the tech sets it to, what is ning imaged. It’s not a number like “five”.

Here is a neat calculator. I use 20 minutes for climbup and climbdown.

I’m sure there studies of the long-term affects on pilots but what do they show?

Cancer rates? Cataracts? Shorter life spans? Genetic mutations in offspring?
