- dkirtley 12y agoThis actually a huge issue for space travel, all of the random electronics and possibly magnetic radiation shielding may be serious. http://www.nasa.gov/directorates/spacetech/niac/westover_radiation_protection.html http://www.nasa.gov/directorates/spacetech/niac/westover_rad...
- dkirtley 12y agoInteresting: ... "scientific research can provide some measure of confidence that short-term, acute exposures up to about 1-2 T [1000-2000 milliT] should be safe... However, it is not possible to determine whether there are any long-term health consequences even from exposure in the milliT range because, to date, there are no well-conducted epidemiological studies with sufficient power to be able to come to any conclusion on this, and there are no good long-term animal studies." http://www1.mcw.edu/radiationoncology/ourdepartment/radiationbiology/Static-Electric-and-Magnetic-F.htm#.VLRAGyvF940 http://www1.mcw.edu/radiationoncology/ourdepartment/radiatio...
