Look at his chart—starts insane-low:
Some Biological Effects of Radio Waves
The following chart was originally published in 2001 and has been updated to comport with current technology.
It is presented here to show just how low some reported biological-effect thresholds are compared with
common modern wireless exposures. The central point is not that every study is identical in design or endpoint,
but that biological effects have been reported across an enormous range of very low power densities—often far
below the levels people assume are biologically irrelevant.
