- jonas21 7y agoThe wikipedia article says skydiving is 8 micromorts per jump. So more like skydiving 50 times?
- medymed 7y agoI don’t think biologic math always works combinatorially like multiple sky dives. This sometime troubles me with radiation dosing comparisons. Another is time distribution, when a radiologic imaging study is equated with exposure from X amount of time in an airplane at high altitude. The time frames are different—- drinking 1 liter of water in an hour is usually safe, and drinking 50 liters of water is fine spaced out over a longer time period—-but not 50 liters over an hour. Radiation doses are often quite time dense.
- semi-extrinsic 7y agoYeah, 1 in 2000 is 500 micromorts, somewhere in the 400-500 micromorts region.
