Electromagnetic fields

Electromagnetic fields, or EMF, can be problematic from two perspectives: the concern over potential health effects from human exposure, and the disruption to computer monitors and other equipment under high field conditions. Our assessment and remediation services can address both issues.

EMF exposure has become a topic of concern for many people and is an active area of biophysical research. Scientific studies in recent years have shown an apparent correlation between exposure to elevated magnetic field levels and the risk of adverse health effects. The same is true for radio frequency radiation from broadcast and cell phone towers. Significant controversy now exists over the degree of risk posed by this exposure, and the exact mechanisms of interaction by which electromagnetic fields may influence biological processes. Confronted with this uncertain risk, many individuals have chosen to take a cautious approach and limit their exposure where possible. Our services address this environmental health concern by providing measurement surveys, field reduction modalities, and building design consultation. We take an objective, information based approach to this issue in which clearly defined guidelines have not been established.

Equipment interference and performance degradation is a commonly encountered EMF effect. A shaky image on a computer monitor is often the first indication that a high field environment exists. In this case EMI, or electromagnetic interference, is the terminology usually employed. Sensitive analytical and research instrumentation can also be adversely affected. An array of EMI remediation modalities, including active cancellation and shielding, are available to counter this problem.
