Radiofrequency Radiation Power Density Levels for Smart Meters, Various Biological Effects, and Exposure Guidelines

Radiofrequency (RF) Radiation Power Density Levels for Smart Meters, Various Biological Effects, and Exposure Guidelines

Introducing a New “Smart” Meter Wireless Radiation Comparison Chart …

There are growing concerns that radiofrequency (RF) emissions from wireless utility “smart” meters cause serious adverse health impacts. Unfortunately, no human health impact studies were conducted prior to the deployment of RF emitting smart grid technologies, which include the smart meters themselves as well as the associated gatekeepers and routers that are part of the overall mesh communications network for each utility’s smart grid system.

In the absence of health impact studies conducted prior to smart meter deployment by utility companies, equipment manufacturers, or health agencies, there have been myriads of anecdotal reports of adverse effects caused by smart meter emissions. In addition, there have been at least limited studies (as listed below) subsequent to smart meter deployments indicating ill-effects:

- “Symptoms Resulting from Exposure to Radiofrequency/Microwave Radiation from Smart Meters,” an article written by Ronald M. Powell, Ph.D. summarizing the results of a health effects survey conducted by Richard H. Conrad, Ph.D.;

- “Wireless Utility Meter Safety Impacts Survey,” by Ed Halteman, Ph.D., dated September 13, 2011;

- “Self-Reporting of Symptom Development from Exposure to Wireless Smart Meters’ Radiofrequency Fields in Victoria,” a case series by Dr. Federica Lamech, MBBS, and described by the American Academy of Environmental Medicine (AAEM) in a document called, “Wireless Smart Meter Case Studies.” [Note: The Lamech case series is in the process of being published in a peer-reviewed journal.]

Peer-reviewed studies as outlined in the BioInitiative Report 2012 support an assertion that adverse biological effects should be expected based upon the RF radiation levels produced from wireless smart meters. For information on published studies showing biological effects from RF exposure from various emission sources, one can review summary information charts contained within The BioInitiative Report 2012, and specifically, relevant charts available at the following link: BioInitiative Report Color Charts for Reported Biological Effects.

Additional support for the claim that adverse effects can be expected from wireless emissions from smart meters can be found in a paper prepared by Ronald M. Powell, Ph.D. at the following link:

Biological Effects from RF Radiation at Low-Intensity Exposure, based on the BioInitiative 2012 Report, and the Implications for Smart Meters and Smart Appliances.”

To more effectively communicate with the public on this topic, a new chart has been prepared (as shown below) to compare:

1. Possible levels of radiofrequency (RF) radiation emitted from wireless smart meters;

2. Bioeffects and adverse health impacts that have been measured “at very low levels” based upon published studies from various emission sources; and

3. Various governmental RF exposure guidelines that do not fully protect public health. In particular, the guidelines for the USA and Canada were only established to protect tissues from significant overheating and electric shock.

The vertical axis of the above chart represents an RF power density for each displayed parameter. The units of measure selected for the vertical axis are milliwatts per square meter (mW/m2). The selected units for the vertical axis work well for relating the RF power density shown to the total RF power that an adult human might receive. The surface area of an adult (male) human is about 2 square meters (m2). So the surface area that an adult human presents to an RF wave arriving from the front, or from the back, is about 1 square meter (m2).

Thus, when an adult human faces an oncoming wave of radiation with a power density of, say, 10 milliwatts per square meter (mW/m2), that human will receive a total of 10 milliwatts (mW) of radiation over the entire body. That is, the number describing the power density will be the same as the number describing the total power received, even though the units of measure are different in the two cases.

Basis information for the above chart values are provided in the linked PDF document shown below. This document is labeled “abbreviated” because a longer version is still being finalized (and will be added at a later date).

The new chart pictured above was developed in cooperation with Stop Smart Meters!
