Microwave ovens work due to the fact that radio-frequThis technology is in the majority of homes and businesses. Precautions to reduce exposure of EMR from microwave ovens encies/microwaves produce dielectric heating of water molecules when produced with enough wattage.  This effect generally affects outer 1” to 1-1/2” of the foodstuff’s water molecules, hence the reason reheating a thick

I have seen blogs and articles on the increase in RF (Radio Frequency) radiation in public places, especially Public Transportation, due to the ubiquity of Wi-fi and personal devices containing transmitters such as smart phones & tablets.  However, I have not seen any information on the low frequency magnetic fields that may be emitted on

Dirty Electricity Concerns? In the recent blog of September 10th, 2013, EMI and LEDs – Not all LEDs are the same! we described dirty electricity and examined several brands of CFLs and LEDs.  This blog tests several more brands of LEDs to determine which produces the least amount of LED dirty electricity . It has

When performing EMF surveys many “EMF consultants” only evaluate low-frequency magnetic fields.  When folks call and say they “have an EMF meter” and are measuring “high emf,” they generally have a Gauss meter and are measuring magnetic field field strength or magnetic flux. Most Building Biologists focus on Alternating Current (AC) electromagnetic fields, and in addition

Do you want to send your kids to an EMF hot-spot with unknown health ramifications? Are some existing symptoms a result of EMF? Reducing exposure to Electromagnetic Fields or Radiation (EMF or EMR) is a contentious debate in public health and green building circles across the United States. OSHA does provide rather liberal exposure limits for

PART 3: Tracking Down Unnecessarily Strong, Stray Magnetic Fields Many people are concerned about the Low Frequency, Alternating Current, Magnetic Field Radiation (further referred to as Magnetic Fields or MF) that is emitted by our modern electrical system and the devices we use every day. The following blog tracks down what can cause residential wiring

How to Measure EMF: The Art of Knowing What You Are Studying There are a lot of people concerned about electromagnetic fields (EMF) and electromagnetic radiation (EMR or also known as radio frequency (RF)).  People want to know how to measure EMF. So much so, that they purchase detectors and meters for themselves and attempt to

This is part of the series on the Healthy Home Standard, and this second part about EMR is a follow up from an earlier post (EMF Rules of Thumb). EMF best practices covers low frequency electric and magnetic fields, as well as Radio Frequency (RF) radiation. EMF best practices are intended to reduce exposure to Electromagnetic Fields

EMF from LED Lights and Recessed LED lights Is there significant amounts of EMF from LED Lights? A designer client of mine had a job she was working on, where her client, a homeowner, was concerned about the magnetic fields in her home.  She was designing a remodel, which included the kitchen, and the designer had

Curious about general best practices for minimizing EMF exposure? This post is an excerpt from the Healthy Home Standard, and it includes many great EMF rules of thumb. This is part of a series about the Healthy Home Standard, and there will be another post on additional EMF best practices. The following EMF rules of
