What is the US Government’s Safety Level Limit for RF Exposure?

At this time, there are no official health and safety legal limits set by the US government for long-term chronic exposure to electromagnetic radiation (EMR). There are only safety guidelines. 

The US regulatory authorities currently recognize EMR (electromagnetic radiation) as a health concern only if it has a thermal effect (heating) on human tissue. The application of a thermal index for determining EMF safety goes all the way back to Herman Schwann’s work for the US Government, in the 1940’s. 

The guideline standards set in 1992 by the IEEE, and then closely adopted by the FCC in 1996, are now seemingly at odds with the NIH's (National Institute of Health) Report of 2017, that stated: “…there is clear evidence that male rats exposed to high levels of radio frequency radiation (RFR) like that used in 2G and 3G cell phones developed cancerous heart tumors, according to final reports released today. (Dated: November 1, 2018)

The reference link is:


 2G and 3G cellphone non-ionizing radiation, which has nothing to do with a thermal consequence, caused this cancer in rats and mice. Therefore, using the thermal index is no longer appropriate.  The S.A.R. index (Specific Absorption Rate) is no longer an appropriate health indicator. When you hold a cellphone in your hand, unless you are a pro basketball player, you are within the near-field (approximately 39 inches) of the magnetic component of 900 MGHz radiation. This is important to realize.

(Note: Today’s smart meters transmit signals from 902 - 932 MHz in the lower lower range up to 2.4 GHz in the upper range, 2G at 900 MHz, and 3G at 850 MHz. Since cellphones transmit at a much weaker power density (Volts multiplied by Amps) than do smart meters, where does logic lead us?)

Today, there is a growing number of health experts calling for our government to revise the current electromagnetic radiation safety standard levels for exposure. Adopting the French and German safety level limits of 10,000 µW/m2 would be a good start. Implementing this higher standard, in NYC, would be a challenge that could present other complications. 


Note: The 869 - 932 MHz range applies to today’s transmissions. It does not apply to the 5G Network, which will be a much higher frequency range. This range has been kept secret from the public.

The FCC's 580 µW/cm2 guideline does not relate to a time-of-exposure. The IEEE C95.1 – 1999 (Institute of Electrical and Electronic Engineers) and ICNIRP (International Commission on Non-Ionizing Radiation Protection) set the limit as 10-million microwatts-per-meter-squared for 30 minutes of exposure, enough to create a thermal effect.

The reference link is:


Most of the world’s RF safety level limit is 10,000 µW/m2 (France, Germany, Russia, China, Switzerland, Italy, Finland, Hungary, Poland, and some countries even lower) all far better than our 5,800,000 µW/m2 guideline; which is not even a safety limit. Here is an example of how ridiculous this number is: two different clients called us this year claiming that their dog and cat were having frequent nose bleeds in their apartments. We find these homes typically have Max Peak levels just below 900,000 µW/m2. That’s 90x’s European limits. It’s clear to us that the US safety guidelines need to be revised. 

(Note: In NYC, we measure many apartments on the 10th floor and above as superseding the 10,000 µW/m2 European safety limit.)
