The health risks due to the exposure of high electromagnetic fields has become a great concern to many people. The fields are everywhere around us – power lines and transformers, appliances, building wire flaws, and stray currents from utilities. Rotech Electric can perform EMF test to assess the levels and danger near and in your home.

These magnetic fields are usually produced by currents flowing in wiring systems. The California Department of Health Services have conducted studies showing there are flaws in building’s wiring systems producing large amounts of magnetic fields. When found, these errors should be eliminated not only because they are dangerous but also in violation of electrical code.

There is an even scarier aspect of electric fields – they can be present even when there is no current flowing. When the voltage is higher, there is a stronger field but voltage can exist even when appliances are turned off. This means that even when your appliances are off EMF can be present. In a residential setting, Romex cable, or unshielded internal wiring, that are present inside walls, power cords, or alarm clocks are usual sources for electric fields. Luckily once these sources are identified, they are usually easily removed.

EMF Phone Consultation

The technicians at Rortech Electric are happy to offer professional phone consultations to discuss your concerns on the EMF in or around your home or work space. We can any any questions you may have about Electromagnetic Radiation, mitigation of EMF, or address any concerns you might have.

Common EMF Questions

  • What can I do about the EMF in my home or work?
  • Are there any levels of radiation that are safe?
  • How can I tell where the EMF are coming from?
  • What is shielding and how can I use it?

EMF Assessment

Rortech Electric is proud to offer EMF assessments or surveys for both residential properties and commercial properties. Since every space is unique, we have learned that measurements for EMF assessments must be taken in different, strategic points in each home or building. Our technicians will then take this information and use it to map out the sources that are emitting the most EMF. This is the most essential step before creating a plan for solution. Without this map a lot of time and money would be wasted with trial and error. Once the source of the problem is found, strategies can be put into place to start reducing the EMF right at the source.

Our Electromagnetic Field surveys are usually conducted when one of the follow has happened:

  • Health safety concerns
  • Interference due to equipment
  • Home or business purchases
  • Designing for low EMF buildings
  • Wiring errors or stray currents

Rortech Electric has the years of experience to help remediate EMF fields in your home or business. We are happy to schedule a consultation with you. Our company wants to create a safe and healthy environment for your family or employees. Contact us to get more information on how we can help you.
