Among hte many things that would happen if an asteroid were to hit us are fire, rocks, and even acid rain. But what I want to know is how could an asteroid cause radiation. They say that an asteroid can't explain the Tunguska event cause an asteroid wouldn't create that high of a level of radiation.
Not likely due to age and decay. Death from below: http://oilismastery.blogspot.com/2008/07/death-from-below.html
The radiation story may stem from the fact that meteorites may contain isotopes; and that most people confusingly associate isotopes with radiation. Or, that certain foreign government departments sometimes use it as a cover story to stop people from finding and selling newly fallen meteorites.
Well it is possible that some of that energy releases in a comet-asteroid impact turns into radiation.
Hum, Yes, i suppose you are right.... http://en.wikipedia.org/wiki/Radiation http://en.wikipedia.org/wiki/Electromagnetic_radiation
