Electromagnetic fields (EMF) are a matter of increasing concern to doctors and health professionals.  In the past 15 years, EMF studies in the United States and in Sweden have demonstrated a link between electromagnetic fields from power lines and certain types of cancers in both children and adults. Just this May, the World Health Organization added cell phone usage to its list of “carcinogenic hazards” because of studies linking the phones' EMF radiation to brain tumors. Yet electromagnetic fields are given off by hundreds of everyday devices – not just cell phones, but microwave ovens, power lines, radio towers and even fish tanks.

Vitatech Engineering is doing something about the problem. The company studies EMF and its effects on human health, and finds ways for people to live and work with EMF-generating systems without endangering themselves. Vitatech's services include EMF surveying, risk assessment, magnetic shielding systems, and EMF training seminars.

Research facilities in universities, hospitals and laboratories often use equipment that puts out huge amounts of EMF radiation. Fortunately, magnetic shielding can block this radiation at the source and protect people working or living nearby. For example, Vitatech recently installed an 800-square-foot magnetic shield in an unused classroom at the University of Arkansas at Little Rock to stop EMF emissions coming from the school's new electron microscopes.

Magnetic EMF shields come in two basic types: passive and active systems. Passive shields use rigid materials and shield wires near the source of the EMF radiation to generate an ongoing magnetic field that's designed to cancel out the EMF radiation. Active shields use electronic feedback to detect EMF and then generate a magnetic field in response. Whether passive or active shielding is more effective in a given situation depends on the nature of the radiation source.

EMF radiation can affect the home as well as the workplace. Houses built under power lines or near large transformers can have dangerously high levels of EMF. Even metal water pipes can conduct the fields into the house. One test that can easily be conducted at home is to hook up a color monitor to a computer, turn both devices on, and rotate the monitor through 360 degrees. If the image on the monitor screen distorts or jitters, there is a strong magnetic field present.

Vitatech has an edge in providing EMF services thanks to the background of its founder and president, Louis Vitale. Vitale originally founded the business in 1984 as a biomedical research company. He developed a portable electrocardiograph (ECG) monitor called the VitaScope for the home health industry, completing the prototype in 1986. Vitatech added EMF survey and engineering services to its repertoire in 1993.

In addition to engineering work, Vitale delivers EMF lectures and presentations regarding perceived threat and public health issues, and leads professional EMF training seminars. He has a B.S.E.E. in electrical engineering from the University of Florida and studied biochemistry at the State University of New York at Stony Brook, giving him an ideal background for understanding EMF and its effects on human health.
