Based upon the scientific evidence set forth in The BioInitiative Report: A Rationale for a Biologically-based Public Exposure Standard for Electromagnetic Fields (ELF and RF) and a large body of additional research, we recommend that the following limits of electromagnetic radiation be set to not exceed:
I. Extremely-low frequency (ELF). Power Lines, appliances, interior electric wiring and other ELF-radiating devices:
A. Homes, schools and places where children spend large amounts of time: 1 milligauss *(1mG) for new construction; 1 milligauss (1mG) for all existing occupied space retrofitted over time.
B. All other construction: 2 milligauss (2mG)
*A milligauss is a measure of ELF field strength used to describe magnetic fields from appliances, power lines, interior electrical wiring,etc. A milligauss, abbreviated, is mG. Just as the power density of high frequency RF fields can be described in µW/cm2 or the corresponding electrical field in V/m, the parameter most easily measured for ELF is the magnetic field.
II. Long-term (cumulative) Radiofrequency Radiation*(RF)
A. Outdoor Pulsed- such as cell phone antennas, radar, TV and FM broadcast antennas, wireless internet antennas: One tenth of a microwatt per centimeter squared or 0.614 volts per meter. * (0.1 µW/cm2 or 0.614 V/m)
*Radiofrequency radiation (RF) power density is measured in microwatts per centimeter squared or volts per metmer and abbreviated (µW/cm2)or (V/m). Radiofrequency Radiation is used when talking about emissions from broadcast, radar and wireless facilities, and when describing ambient RF in the environment. In the United States and Canada, for example, the amount of allowable RF near a cell tower is one thousand microwatts per centimeter squared (1000 µW/cm2) for some cell phone frequencies.
B. Indoor Radiofrequency Radiation (RF) such as cell phones, wireless internet equipment and the radiation that permeates buildings from outdoor sources. One hundredth of a microwatt per centimeter squared or 0.194 volts per meter (0.01 µW/cm2 or 0.194 V/m). Typically, RF power density from higher frequency outdoor sources such as UHF television or cell phone antenna base stations drops by a factor of ten when it permeates buildings. Lower frequency signals such as lower channel VHF TV and FM are not as severely attenuated as the higher frequencies.
