One of the major concerns in Building Biology are EMF and EMR.

From Wikipedia: An electromagnetic field (also EMF or EM field) is a physical field produced by electrically charged objects. It affects the behavior of charged objects in the vicinity of the field. The electromagnetic field extends indefinitely throughout space and describes the electromagnetic interaction. It is one of the four fundamental forces of nature (the others are gravitation, weak interaction and strong interaction).

From that definition is becomes clear that EMF may effect humans, after all, the human body communicates via small electric currents. I say “may” as there are plenty of reports that it does and also plenty that it does not. It is a similar situation as with cancer. For a summary of reports you could have a look on the EMF & EMR pages of the International Institute for Building Biology & Ecology.

Sources of non-thermal electromagnetic radiation (EMR) are ubiquitous: microwave towers, high-power lines, electrical transfer/relay stations, Smart Meters, cell phones and Smart Phones.

It is vital to note that the above sources of EMR are non-thermal: they do not generate heat, and therefore provide you with no early warning, no physiological means by which most people can recognize that they are causing harm at a biological and metabolic level.

There are three forms of electromagnetic radiation that emanate from manmade devices: static electric and magnetic fields, AC electric and AC magnetic fields, and radio frequency radiation. The potential risks they pose to human health vary in accordance with field, field strength, voltage, current, charge, grounding, frequency, wavelength, and power density.  There are countless scientific studies that portray the ability of EMR to adversely affect humans (as well as plants and animals) at the cellular level, studies that show they diminish the ability of cells to defend themselves, and disrupt a cell’s natural ability to produce healthy new cells.
