- api 15y agoAgreed. Maybe long distance manned space flight will finally kill radiophobia.
- Groxx 15y agoFollowing that math, the 9 day Apollo trip got 0.0114 sieverts. We'll round that to 11 mSv. So in 9 days, they got 11x more than the EPA's yearly limit to the public, or 1/5th of the EPA's yearly limit to radiation workers. The 520mSv warpspeed listed as a trip's radiation exposure comes out to 5x the lowest yearly radiation exposure 'clearly linked' to increased cancer risk. So yeah. A problem, barring adequate shielding, if that number is correct.
