Reported Biological Effects From
Radiofrequency Non-Ionizing Radiation

The following studies indicate biological effects at exposure levels far below what would be explained by "thermal effects", and well within the range people are commonly exposed to every day.

NOTE: Most of these exposures lie FAR BELOW the current advisory exposure standards in the US, which are based on thermal effects only.
