Wave activity was confirmed in indicator of tsunami in coastal Chatham Islands at 07:35 am ET in New Zealand local (18:35 GMT Saturday), New Zealand's Ministry Civil Defense and Emergency Management (MCDEM) announced. At this stage, the change in sea level …

Radio Waves Bane or Blessing?

RADIO WAVES Bane or blessing?

     The evolution of man in the wisest of beings in this universe can be considered as natural blessings, but their mental, spiritual and technical advances are the result of their struggle, effort, and effort. We have seen how technology evolves with the development of human society. From the historical pre Timea € ™ s technology for use of fire for agriculture have been the major benchmarks, with the success of each technology development rate also has increased. Â

     That the communication is a milestone and has also written a story in itself same. Of pigeons flying to the 3G communication has trodden a long way. The improvement and progress in this field has squeezed everyone in the global village.

    Â

     But the other side of this is a totally different story to tell, indiscreet use of communication technology has done more harm than good to our society today.

    Â

     Over the years the population of birds has seen massive decline due to the presence of radio frequency (RF) in the environment, these waves RF are electromagnetic waves that leads to heating of the body that eventually affected avian creatures.

          Â

     And not only that our human population is on the verge of the harmful effects of RF waves, today we have lakhs of mobile phone towers called base stations (BS), led by dozens of mobile operators in India, each radiating electromagnetic radiation dangerous in this environment, studies show that exposure to electromagnetic fields (EMFs) thus created has adverse health effects it causes a noticeable deterioration in the health of exposed individuals or their descendants.

    Â

     Exposure to electromagnetic fields at frequencies above 100 kHz can lead to absorption significant energy and temperature increases. Resulting in highly non-uniform deposition and distribution of energy in the body, much controversy over the possibility relationship between EMF exposure and increased risk of cancer. After extensive research and development has not found an association between mortality Childhood cancer and radio waves, leukemia accounts for about one third of all cancers in children under fifteen (15) proximity of home to power TV, RF distribution lines generation high current configuration is suspected that the main reason behind this rule.

     Another research mind boggling is that X-ray examinations during pregnancy i, and the mother's prenatal exposure to diagnostic X through ray procedures also revealed a clear link between exposure to risk.

    Â

     Some study refers to the psychological risks that may be directly related to the implementation of a particular technology, such as a mobile phone tower base station next to a school or residential community, are the psychological risk change in blood and urine chemistry, changes in cardiovascular reactivity, skin conductance and sleep patterns can also cause the person unless resistant to infectious diseases with fragile immune system. Under conditions of partial body exposure to electromagnetic fields, thermal damage important may occur in sensitive tissues such as eyes and testes. At very high frequencies (10-300 GHz) electromagnetic energy absorption is limited primarily epidermal layers of skin, subcutaneous tissue, and the outer eye.

    Â

     To protect this world of the living from the adverse effects of RF waves, most European and other developed countries are being governed by the Board of â € œInternational on non-ionizing radiation protection € (ICNIRP). In this country, DoT has asked mobile operators to give self-certification, DOT also wanted to control the emission level according to the rules ICNIPR. Thanks to Dot at least remembering to do so, but honestly to remain at this certificate we all know. No preference goes to the cheap and rapid dissemination network that will give them maximum benefit. As one of the main Cellular operators œBhartiâ € â €, is busy producing hundreds of probes as the net profit each quarter, however, not known to what point (ICNIRP) are within the parameters of such mobile operators in India.

    Â

     Although in our country Regulatory Authority of Telecommunications of India exists, but so far has proved totally inept to address the deficiencies in its rules and regulations, so much so that most existing cellular operators radiate frequencies beyond what they are authorized to.

    Â

     One important thing that can summarized the previous discussion is that before implementing any new technology, itâ € ™ s validity with the perspective of human society must be verified. Because of one technology over thousands of us can give comfort, but eventually gives birth to the same amount of deterioration that are disastrous for this one planet land living flame.
