Electromagnetic Radiation (EMF)

Microwave Ovens and EMR Exposure Precautions

EMR from microwave ovens
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

Not All LED’s are the Same (Addendum)

LED Dirty Electricity
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

Magnetic Fields – EMF Consulting

Magnetic Fields - EMF Consulting
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

EMF at High Performance Schools

Kids Going To High EMF School?
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
