It is simply a matter of using references that people are comfortable with. Meteors in the range of very bright fireballs to impact events happen to produce energy levels that are equivalent to nuclear bombs. Unlike nuclear bombs, however, the energy released by meteors and impacts is substantially non-ionizing. And the processes involved in the release of energy are completely different. As an aside, some meteors are detected by instruments that are designed to record nuclear blasts. Those instruments are normally calibrated with energy units in tons of TNT. Depending on whether energy data is presented in joules or in tons of TNT, you can sometimes guess what the monitoring agency was really looking for <g>.

There seem to be a lot of references and explosive asteroid events are often measured in Hiroshima bombs to scare the hell out of people. I always asked myself the question why that is? Is there not a different process at work, that of nuclear fission (atom bomb) and fusion (hydrogen bomb)? But when considering Tunguska, the aftermath seems to be very similar. I would like to know more about this: There has been accelerated tree growth due to the radiation, have there been any cases of mutations or illnesses of animals? Is such a radiation as severe as that of a bomb? And what is the difference / similarity of Tektites and Trinitite? Regine Received on Mon 17 Jan 2011 05:07:14 PM PST |
