Hey moron, I gave you the number if 100% of that 1/10 watt is absorbed.
It is *still* too low to cause a significant increase in temperture.

You said it was the "standard", and standards for that are set to be
safe to the best of our knowledge.

I gave you the results for radiation inside a conductor, and you
ignored that. The ideat that the standard is "too high" by "2-3
orders of magnitude" is simply an unsubstantiated conjecture of
yours.
BTW, in case you don't know, you are surrounded by electromagnetic
radiation from natural sources: at room temperature, a blackbody emits
about 45 mW for every square cm of surface area. (Actually, I rounded
to 300 K.) The frequency where the spectrum reaches its maximum,
however, is well above the range used by cell phones (but MV had
previously decided to discount frequency as a factor for some
strange reason.)
