specific absorption rate

[Robin Paulson]

i was looking through planet earlier, when i saw this blogpost, which
i'm sure others of you have read:

http://blogs.thehumanjourney.net/finds/entry/20080901

i gather it's a report on the effects of emitted radiation when the
freerunner is used near to a person's body. is there anyone here who
understands these things. would it be possible to explain what this
means, in a more condensed terms and understandable way?

i'm not looking for 'The Idiot's Guide to Mobile Phone Radiation', or
anything like that, but something a bit simpler to understand. I'm
sure there are others here who would be interested to here this too

thanks
