The next time you use an I-Pod, a microwave oven or a high-speed food processor, make sure you are not exposed to harmful electromagnetic radiation (EMR) that may lead to irritation, violent mood swings or sleeplessness, says a recent study.
The study by Cogent EMR Solutions Ltd, a leader in the field of anti-EMR technology and a member of the Global Wellness Foundation, has found that EMR, a self-propagating wave with electric and magnetic components, poses a major threat to human health due to excessive use of electronic devices.
Carried out with the help of four scientists associated with Defence Research and Development Organisation (DRDO), it found that EMR rates in Delhi, Mumbai and Bangalore were much higher than the permissible limit.
It can cause irritation, violent mood swings, sleeplessness, lack of concentration, low sperm count and cancerous diseases, Haq said, adding that they would conduct a similar study in Kolkata next month.
He said mobile phone towers were also a potential source of powerful EMR. Medical experts, however, underplayed the alarming findings, saying there was no documented evidence to prove that electronic products like mobile phones and microwaves caused health hazards.
"Though EMR has some potential to penetrate human tissues, there is no documented evidence to prove mobile phones, microwave ovens or other household electronic products radiate EMR," said NRS Medical College and Hospital oncology head Subir Ganguly.
Admitting the dangerous effects of EMR, Sukalyan Chattopadhyay of the Saha Institute of Nuclear Physics said electromagnetic waves do damages human tissues.
Chattopadhyay, who is also associated with Big Bang Theory research at CERN in Geneva, added: "Each type of human tissue has certain power to absorb frequency level and if that level exceeds, it does affect human health to a great extent."
He explained that EMR is categorised into several types considering its frequency of waves. These include radio waves, microwaves, terahertz radiation, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
EMR carries energy and momentum that might be imparted when it interacts with other matter, he said.
The Cogent EMR study for determining the effect of hazardous EMR revealed that exposure of human blood lymphocytes to continuous resonant frequency (RF) radiation of 830 MHz electromagnetic fields for 72 hrs - at temperatures ranging from 34.5 to 37.5 degrees Celsius - could lead to fatal diseases.
Such RF radiation is emitted by high-speed electronic devices, including microwaves, hair driers and automatic shavers.
It found that growing exposure to electric transformers that emit 50-60 hertz low level electromagnetic fields (EMF) may block melatonin, a type of natural neuro-hormone produced by the brain. It can also affect the ability of melatonin to suppress breast cancer cells from further multiplication.
Melatonin helps maintain body temperature and cholesterol levels by reducing risk of coronary heart disease and chances of blood pressure.
It was also observed that eight hours of radiation from a TDMA (times division multiple access) cell phone could result in a 40 percent increase in ornithine decarboxylase (ODC) enzyme level, an indication for increased multiplication of cancer cells.
The study further revealed EMF exposure through mobile phones may affect rapid eye movement during sleep.
