In 1993, Canada Mortgage and Housing funded a study looking at the prevalence of electromagnetic fields (EMFs) in Canadian homes. Almost 50% of homes showed elevated levels of EMFs due to electrical wiring errors. These were levels of exposure above that which has been shown to be associated with illness in the public. Powerline EMFs, combined with Wi-Fi and cell phone radiation, may also place a huge burden on our immune systems and spawned a new category of illness known as electro hypersensitivity. Protect your health. Have your home and workplace tested for EMFs and limit your use of wireless technology.
