101. EMF Exposure - Risk Assessment - Remediation Provides electromagnetic field measurement surveys, remediation services, and home design consultations. http://www.emfservices.com/index.htm

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.

VitaTech engineers and installs shielding systems in commercial buildings, nanotech, research, medical and hospital facilities. We specialize in high performance AC ELF (extremely low frequency) shielding systems for electrophysiology research and diagnostic rooms (EEGs, EKGs, EMGs, etc.), combined AC ELF/DC shielding systems for high resolution electron beam research tools (TEMs, SEMs, STEMs, FIBs, E-Beams, etc.) and AC ELF/DC/RF shielding systems for NMRs, MRIs and MEGs. We also offer DC Active Compensation System (ACS) technology to ensure optimal low-noise quasi-static environments in all our shielded rooms.
