Are cell towers, power lines, and wifi affecting EMF/EMR in your building?

EMF Testing / Consultants

Electromagnetic Field Testing and Inspections (EMF/EMR)

Do you need EMF Testing? Employee complaints or need a second professional opinion regarding EMF exposure? Need an FCC survey for cellular antennas on your roof before a construction project? City or town concerned that telecommunication companies are not in compliance with FCC emissions standards? About to purchase a building near a power line and curious about magnetic fields? Healthy Building Science offers professional EMF testing, consulting and surveys for magnetic fields, electric fields, high-voltage transients, Radio Frequency radiation (RFR) and ionizing radiation.

We support two primary groups of customers. Some require regulatory testing to ensure compliance with OSHA or FCC allowable emissions standards, and others are just curious or sensitive and trying to determine what is present and how to reduce exposures. Magnetic field, ionizing radiation, and RF compliance surveys are larger projects that require specialized equipment and formal reports referencing allowable levels. Most often working environments do not exceed allowable limits. Oftentimes a local utility provider, like PG&E for power lines (magnetic fields) or Verizon for cellular service (radio frequency radiation), will provide their own surveys and reports free of charge. However, there are times a property owner may want a second opinion or be looking for best practices and tips for mitigation in order to reduce exposure levels even further below allowable limits. Our professional EMF testing and consulting services start with a survey and report of what is measured onsite and may include detailed instructions on how to mitigate and further reduce exposures.

The other segment of our electromagnetic radiation (EMR) clients are electrically sensitive and have difficulty sleeping, get headaches or ringing in the ears, or have other symptoms from electrosmog. We help these EMF-sensitive clients create more natural and health-supporting spaces by reducing artificial electromagnetic fields (EMFs) at their home or work environment. Symptoms of electromagnetic sensitivity (headache, muscle tension, sleeping disorders) can be debilitating. Electromagnetic radiation is invisible and can be extremely complex. Without knowing sources or understanding mitigation strategies, do-it-yourself approaches can do more harm than good. Professional EMF testing is important.

Professional consulting and pre- and post-mitigation emf testing provide certainty and peace of mind.  Many common EMF mitigations are zero cost or even save money, while others may be more involved and include remodeling, painting, applying shielding window films, etc.. Mitigation is not always necessary but if required Healthy Building Science EMF consultants can provide specific instructions and help with mitigation efforts.

EMF Consultant San Francisco

HBS has the training, equipment necessary, and protocols (FCC, OSHA, Building Biology– adopted from Germany) to evaluate your building for EMF and suggest practical and effective mitigation strategies. We regularly identify wiring errors (electrical code violations) that lead to elevated magnetic fields in buildings. By working with electricians we are able to identify and correct the wiring error and the magnetic fields are reduced instantly to normal background levels. Radio frequency (RF) mitigation is accomplished by installing additional materials such as screens, paints, and foils in walls, floors and roof assemblies. Costs and time on site vary depending on the location and size of the building. We consult on agency buildings, hospitals, schools, multi-family, and single-family homes, offices, and manufacturing facilities.

Electromagnetic Field (EMF/EMR) Projects

We provide expert EMF testing for all building types and focus primarily around the San Francisco Bay Area.

  • Radio Frequency testing for San Francisco schools
  • Magnetic field inspection for San Jose affordable housing development site
  • San Rafael FCC compliance survey for public building
  • Napa EMF survey for public building
  • Oakland EMF testing and home inspection
  • Los Altos Low-EMF design consulting for existing home
  • San Francisco EMF consulting for new remodel
  • Berkeley school EMF survey

What do EMF Survey’s Include?

EMF inspections can identify significant internal and external sources of EMF and RF exposure, determine if utilities are carrying stray current, find likely wiring code violations leading to elevated magnetic fields, etc. The scope of work may include testing for “dirty electricity” or “electromagnetic interference,” and specifying line conditioning equipment. The survey includes testing for low-frequency electric and magnetic fields, and radio frequency (RF) radiation, on the four corners of the site and building as well as at all “high use” areas. Discussion and possible testing of basic approaches to mitigation are included. And detailed instructions, as well as installation support, are available upon request.

EMF Commercial Survey & Site Evaluation 

Traverse the site and collect measurements for AC magnetic fields and/or Radio Frequency (RF) radiation. Readings will be collected at a minimum of the 4 corners of the property, and depending on the needs of the project we can walk transects across the property collecting measurements at specific locations upon request. If measurements are required more than 8ft off the ground, a cherry-picker or scissor-lifter will be rented to help collect elevated measurements. Depending on project requirements reporting will be done via email or transcribed on an aerial photograph.

Healthy Building Science is an environmental consulting firm which provides EMF testing, RF testing, inspections, surveys, assessments and consultations for the greater San Francisco Bay Area and all of Northern California including the cities of San Francisco, San Jose, Oakland, Sacramento, Santa Rosa, Hayward, Sunnyvale, Fremont, Concord, Salinas, Santa Clara, Berkeley, Vallejo, Fairfield, Antioch, Richmond, Daly City, San Rafael, San Mateo, Vacaville, San Leandro, Livermore and Alameda County, Contra Costa County, Marin County, Napa County, San Mateo County, Santa Clara County, Solano County and Sonoma County.

Electromagnetic Inspections Benefits and Services

Electromagnetic Inspections Benefits and ServicesOur training, experience, and technology are unique in this area of environmental assessments. HBS uses finely calibrated metering equipment and a proven protocols to analyze buildings for electrosmog. Surveys can take between 2-6 hours, depending on the complexity of the case. We usually focus on low frequency EMR in the sleeping and working areas, and high frequency Radio Frequency throughout the building. We are also often called upon to survey property without any buildings. The final report includes a site/floor plan with meter readings, and suggestions for mitigation.

Electromagnetic inspections commonly include:

  • AC Electric Fields (60 Hz - appliances, lamps, clocks, cords, plugs, etc.)
  • AC Magnetic Fields (60 Hz)
  • Radio Frequency (High Frequency - cordless phones, Wi-Fi, microwave ovens, etc.)
  • Dirty Electricity (aka: "noise," or "high-voltage transients")
