The EPA: In official comments to the FCC about guidelines for evaluation of electromagnetic effects of RF radiation (FCC Docket ET 93-62, November 9, 1993), The Environmental Protection Agency found that the FCC's exposure standards are "seriously flawed."
The FDA: The Food and Drug Administration commented to the FCC on November 10, 1993, that "FCC's rules do not address the issue of long-term, chronic exposure to radiofrequency fields."
In 1999, the Radiofrequency Interagency Work Group wrote a letter to IEEE SCC28, in which they identified fourteen issues that "need to be addressed to provide a strong and credible rationale to support RF exposure guidelines."
Yes. There are several reports of adverse health effects from low levels wireless (or radio frequency radiation) that our government actually wrote and participated in.
