The electromagnetic spectrum encompasses a wide variety of frequencies including the earth’s magnetic field, sound, radioactivity, x-rays and cosmic rays. We are exposed to many of these frequencies on daily basis. Some, like visible light and sunshine are essential to human health; others such as those used in telecommunications, household appliances and building wiring may pose a health risk.
Human beings are bioelectrical systems. Our hearts and brains are regulated by internal bioelectrical signals. Environmental exposures to artificial EMFs can interact with fundamental biological processes in the human body. In some cases, this may cause discomfort, or sleep disruption, or loss of wellbeing (impaired mental functioning and impaired metabolism) or sometimes, maybe it is a dread disease like cancer or Alzheimer’s disease. It may be interfering with ones’ ability to become pregnant, or carry a child to full term, or result in brain development changes that are bad for the child. It may be these exposures play a role in causing long-term impairments to normal growth and development of children, tipping the scales away from becoming productive adults.
The range of possible health effects that are adverse with chronic exposures has broadened. The most serious health endpoints that have been reported to be associated with extremely low frequency (ELF) and/or radiofrequency radiation (RFR) include childhood and adult leukemia, childhood and adult brain tumors, and increased risk of the neurodegenerative diseases, Alzheimer’s and amyotrophic lateral sclerosis (ALS). Recent studies largely reinforce the potential risks to health (rather than reducing our concerns, or providing actual indications of safety).
In addition, there are reports of increased risk of breast cancer in both men and women, genotoxic effects (DNA damage, chromatin condensation, micronucleation, impaired repair of DNA damage in human stem cells), pathological leakage of the blood–brain barrier, altered immune function including increased allergic and inflammatory responses, miscarriage and some cardiovascular effects. Insomnia (sleep disruption) is reported in studies of people living in very low-intensity RFR environments with WI-FI and cell tower-level exposures. Short-term effects on cognition, memory and learning, behavior, reaction time, attention and concentration, and altered brainwave activity (altered EEG) are also reported in the scientific literature. Biophysical mechanisms that may account for such effects can be found in various articles and reviews. (Bioinitiative, 2012)
Current exposure limits in most countries are based on thermal effects (how much parts of your body heat up). These exposure limits are far higher than Building Biologists and many health experts would like. It is important to realise that the standards are not based on biological effects and therefore there is no way of knowing what the long term health effects of electromagnetic radiation will be. The exposure limits in Australian are 100 times higher than some other countries. Whenever electromagnetic radiation testing is conducted in homes the levels are always a fraction of the Australian exposure limit and are therefore deemed not to be a problem by telecommunication companies and some governments.
