What Can You Do About EMF?
Mitigation Solutions

Successfully mitigating an existing EMF problem typically involves several phases.

• As first step, it is necessary to conduct an EMF survey of the area or areas of concern. An EMF site survey involves the measurement or "mapping" of EM field levels in the affected area to determine their exact magnitude and characteristics and location of the offending source.
• In the next phase, measurement and other data collected during the EMF site survey, is analyzed and used to develop a range of possible mitigation measures.
• A third step is the actual implementation of an optimum mitigation solution.
• A post-mitigation EMF survey confirms by measurement, that elevated EMF levels in the area of concern have been adequately reduced by the mitigation.

DC magnetic fields, AC magnetic fields and RF radio frequency fields, usually each require distinctly separate and differing mitigation techniques. However, all EMF problems, irrespective of frequency, typically employ one or more of the following mitigation strategies:

• Create or increase distance between the EMF source and the affected area or device
• Decrease or minimize EMF emission field strength from the offending source
• Shield either the EMF source or affected area and/or device

Although well experienced with mitigation of EMF problems at all frequencies, FMS has developed exceptional expertise with the mitigation of AC magnetic fields. The mitigation of AC magnetic fields is an extraordinarily difficult challenge, as magnetic fields at this very low frequency, tend to pass undiminished through almost any conventional material including earth, concrete, lead and most commercial building materials.

Hence, the following mitigation solutions are presented for reducing AC magnetic fields.
