If there really were a health hazard from cell phones, microwaves, and other Gigahertz and lower radio emitters, then we wouldn't be seeing a few isolated cases, we'd be seeing a MASSIVE and rampant outbreak of problems.
Now it is true that all radio waves DO interact somewhat with living tissue, and the lower the frequency the less the interaction. Microwaves at high power levels will obviously cook meat, so you don't want to get a body part in a high-level microwave field. But UNLIKE ionizing radiation (X-rays, gamma rays), exposure to LOW LEVEL radio waves does not "accumulate" over time and cause damage equivalent to a shorter high-level dose. There's a threhold effect- if the level is low enough that it doesn't cause local heating of tissue, then no damage is done.
The guy has taken a real phenomenon and extrapolated it to the point of buffoonery.
