Electromagnetic radiation ( EMR ) is energy in waves ( like visible light ), emitted from a source. It travels at the speed of light. This energy is both electrical & magnetic. The waves alternate rapidly, from positive to negative in electrical terms., & from north to south pole in magnetic terms. Electricity& magnetism are very closely related in nature. For example, when an alternating magnetic wave penetrates a body ( including yours ) an alternating electric current will flow inside that body. Electromagnetic radiation from a source , & weakens with increasing distance until it becomes too small to measure. http://eco-friendly-ctn.blogspot.com/2011/11/effects-meaning-of-electromagnetic.html
A strong EMF can be due to a powerful source of radiation far away, or a weak radiation source very close by. That is why the EMF your body experiences from your cell phone ( when you make a call ) is much stronger than the EMF you experience from the cell phone tower. ( Although the cell phone is a weak radiation source , it is located very close to your person, whereas the much more powerful cell tower is located thousands of times further away ). Extremely Low Frequency ( ELF ) radiation will actually penetrate concrete pillars , concrete slabs & metal sheets & of course human flesh & bone.
Penetration is a Key issue when it comes to EMR health effects.
Modified Currents and Voltage generate oscillation of the electrical and magnetic field, which propagates in space.The electric & magnetic components oscillate at right angles to each other, these waves are termed as Electro Magnetic Radiations ( EMRs).The Cell phone Towers emit electro magnetic rays with a frequency of 1900 MHz. With this high frequency, they can easily pass through human bodies & concrete walls. Our immune system can be harmfully affected when these EMR rays pass through our body Cell phone towers radioactivity can thus affect every living thing in one square kilometers.
People who live in a high- EMF Neighbourhood — Anyone who lives within range of Electric power lines or cell phone Towers for several ( Five ? ) years or more ( and especially children ). The range depends on the electromagnetic field strength & distribution pattern. Generally 400 meters or more seems to be a safe distance for most power lines/Cell phone Towers. It is worth noting that when the body is overwhelmed by too much electromagnetic radiation, health effects can occur many years later.
In India Telecom Department have not made compulsary in most sites with ‘warning signs’ visible,saying “Danger RF Radiations, do not enter , restricted Area ” as in case of High Tension Power Transmission Electric lines are seen with Danger signs.
