If it is a major overexposure, a few days or a week perhaps. Small overdoses may take years to produce any effect, then it may be argued these are just effects of ageing or exposure to chemicals etc. Radiation sickness is therefore reserved for sickness arising due to known massive overdoses.
if there is radiation in the vacuum, then it's not really a vacuum.
Don't go into one, disable the safety mechanisms, and take a bath in the core. A properly operated nuclear reactor, breeder or otherwise, is safer to live next to even in terms of radiation than a comparably-sized coal-fired power plant. Of course, if it's being run improperly (Chernobyl), it's not safe, but the only solution to that is "move."
radiation
The type of energy transfer that can take place with little or no matter present is radiation.
it doesnt
No
2 to 3 months
1 hour guessing.
For me it took about 1 and a half to 2 yrs
it depends on how severe it is and how well you responded to it
It was a health hazard immediately
Russia, the nuclear plant was in the place called chernobyl :)
Chickenpox take roughly 2-3 weeks to heal, scab over and start to fade.
Bruises don't scar. They can take a long time to fade though.
1.) How long did it take for the radiation levels In Hiroshima to go back to normal ?
It depends on how fast ur hair grow. But it usually take 3-5 months
