Ambient man-made electromagnetic fields (EMFs), across a range of frequencies, are a serious environmental issue. Yet most environmentalists know little about it, perhaps because the subject has been the purview of physicists and engineers for so long that biologists have lost touch with electromagnetism’s fundamental inclusion in the biological paradigm. All living cells and indeed whole living beings, no matter what genus or species, are dynamic coherent electrical systems utterly reliant on bioelectricity for life’s most basic metabolic processes. It turns out that most living things are fantastically sensitive to vanishingly small EMF exposures. Living cells interpret such exposures as part of our normal cellular activities (think heartbeats, brainwaves, cell division itself, etc.) The problem is, man-made electromagnetic exposures aren’t “normal.” They are artificial artifacts, with unusual intensities, signaling characteristics, pulsing patterns, and wave forms, that don’t exist in nature. And they can misdirect cells in myriad ways. Every aspect of the ecosystem may be affected, including all living species from animals, humans, plants and even microorganisms in water and soil. We are already seeing problems in sentinel species like birds, bats, and bees. Wildlife is known to abandon areas when cell towers are placed. Radiofrequency radiation (RF)—the part of the electromagnetic spectrum used in all-things-wireless today—is a known immune system suppressor, among other things. RF is a form of energetic air pollution and we need to understand it as such. Humans are not the only species being affected. The health of our planet may be in jeopardy from this newest environmental concern—added to all the others. Citizens need to call upon government to fund appropriate research and to get industry influence out of the dialogue. We ignore this at our own peril now.

Units Conversion
EMR Issues - EMF/EMR General Information

Many people are wanting conversions between microwave measurement units so that they can compare Volts per metre (V/m), with Watts per metre squared (W/m2). For modern digital telecommunications signals, this is not as easy, or as useful, as you would first think that it would be.

For continuous-wave transmissions, including VHF FM radio signals, the conversion is relatively easy.
These signals remain fairly constant in amplitude and the conversion from signal strength in volts/metre to power flux density (PFD) in watts per square metre can be done using the formula:

PFD = (V/m)2/377 watts per metre squared (W/m2)

e.g. 58.2 V/m (ICNIRP 1800 MHz) = (58.2*58.2)/377 = 9 W/m2

This conversion is not particularly relevant for exposure from mobile phones, base stations and DECT cordless phones and the results can be extremely misleading.

The problem occurs because PFD is ONLY relevant to heating and it averages the power over time (6 minutes for official RF PFD measurements). Any PFD has to be integrated over time and most hand-held instruments average over at least a few seconds. Some instruments have a "peak-detect" facility that can give the equivalent power as if the pulsing peak levels were continuous. Note this is not the same as a "max hold" facility. This is because the normal max hold function on a meter gives you the maximum RMS value measured over the time you have been using the instrument, whereas peak detect measures the level at the top of any pulses in the signal.

For example, the peak power from a TETRA base station is twice the average power.
The peak power of a DECT cordless phone base unit can be up to 100 times more than the average power!

We believe that the best unit of measurement for varying microwave signals at the non-thermal levels we are concerned with is volts per metre. Most instruments that display PFD units have actually measured the signal in terms of V/m and then internally calculated the equivalent (usually average) PFD value in W/m2 or similar.
