Appendix A Health & Safety Certification
Radio frequency electromagnetic fields may pose a health hazard when the fields are intense.
Normal fields have been studied extensively over the past 30 years with no conclusive epidemiol-
ogy relating electromagnetic fields to health problems. Detailed discussions on the subject are
contained in the references and the web sites listed below.

The USA Federal Communication Commission (FCC) and Occupational Safety and Health
Administration (OSHA) both specify acceptable levels for electromagnetic fields. Similar power
levels are mandated by corresponding agencies in other countries. Maximum permissible expo-
sures and time duration specified by the FCC and OSHA vary with excitation frequency. The low-
est threshold plane wave equivalent power cited is 0.2 mW/cm
