All the transmitting towers, such as AM and FM towers, TV towers, cell towers, etc. emit RF/microwave radiation continuously. Also, Wi-Fi (wireless Internet), wireless computers,cordless phones and their base units, cell phones and all other wireless devices emit microwave radiation. A cell phone that is ON but not in use is also radiating.
Cell phones operate within the frequency band of 800 MHz, 900 MHz and 1800 MHz and the latest 3G technology works between 1900 -2200 MHz. Computers and laptops operate within the frequency range of 1000 -- 3600MHz, and most Wi-Fi systems and some cordless phones operate around 2450 MHz, which is same frequency as that of a microwave oven! The growing use of wireless communication in the last decade has introduced concerns about health risks from the so called man made electro smog. Various epidemiological and experimental studies have been carried out and the results have shown to have a close relation between biological effects and
Electromagnetic radiation (Sage Cindy et al 2009).
Microwave radiation effect can be classified as - thermal and non-thermal. The thermal effect has been largely studied and refers to the heat that is generated due to absorption of microwave radiation. Being exposed to the thermal effect could cause fatigue, cataracts and reduced mental concentration. Research is going on to study the non-thermal effects of radiation, and it has been associated with affecting the cell membrane permeability. Sadly the current exposure safety standards are purely based on the thermal effect while ignoring the non-thermal effects of
Principle of microwave heating is similar to that of a microwave oven where the water in the food content is heated first. Likewise microwave absorption effect is much more significant by the body parts which contain more fluid (water, blood, etc.) like the brain which consists of about 90% water. Effect is more pronounced where the movement of the fluid is less, for example, eyes, brain, joints, heart, abdomen, etc. The effect has shown to be much more severe for children and pregnant women.
Of late there are lots of reports coming out on how radiation through mobile towers causes cancer, though cell phone companies maintain that there is nothing conclusive on this subject.
The effectiveness or seriousness of the issue has not been realized among the common man yet as one can not see or smell or hear microwave and its effect on health is noted after a long period of time. Therefore, majority of the people tend to have casualness towards personal protection.Unfortunately, ignorance and non-awareness adds to this misery and all of us are absorbing this slow poison unknowingly.
