Radiation Dose Chart

For people, like me, who are confused about all of
the numbers about radiation does, a friend of mine 
directed me to a "Radiation Dose Chart" that provides
a relative chart of radiation does from different sources.

The Radiation Dose Chart can be found at:

http://xkcd.com/radiation/

As the chart states, it is for education only.

The weirdest thing that found was environmental
tours of the Chernobyl Power Plant as seen at

These are a heartbreaking and tragic preview of what will 
eventually happen to the northwest coast of the United 
States and west coast of Canada. It happened in 1700 and
other times in prehistory to these areas and will occur again.

Elongate Possible Simutaneous Multiple Impact Crater Found On Mars

Satellites See Evidence of One-Two Asteroid Punches on Mars
Wired Science, Lisa Grossman, March 4, 2011

A slug-shaped crater, which lies in Mars’ heavily cratered 
southern highlands and just south of the Huygens basin,
appears to represent a chain of impactors hitting Mars at 
shallow angle. The image is at:
