My air filter was measuring more than 30 mhz. I never expected that! July 29, 2006Posted by healthyself in Blogroll, Cell phone safety, Electromagnetic pollution, EMF's, Environment, radiation.
If you add up all the electromagnetic frequencies in your house, and then in your car, and then in your office, you may be surprised how how you may be being cooked.
The NCRP, IEEE, and ICNIRP all have identified a whole-body Specific Absorption Rate (SAR) value of 4 watts per kilogram (4 W/kg) as a threshold level of exposure at which harmful biological effects may occur. Exposure guidelines in terms of field strength, power density and localized SAR were then derived from this threshold value. In addition, the NCRP, IEEE, and ICNIRP guidelines vary depending on the frequency of the RF exposure. This is due to the finding that whole-body human absorption of RF energy varies with the frequency of the RF signal. The most restrictive limits on whole-body exposure are in the frequency range of 30-300 MHz where the human body absorbs RF energy most efficiently. For products that only expose part of the body, such as wireless phones, exposure limits in terms of SAR only are specified.
