Level of exposure (power) is inversely proportional to the square of distance from top of the tower (where antenna is located)

Excerpt from Experts in Health Physic Society (please see hps.org link attached): "Radiofrequency (RF) emissions from antennas used for wireless transmissions such as cellular and PCS (personal communication systems) signals result in exposure levels on the ground that are typically thousands of times less than safety limits. These safety limits were adopted by the FCC based on the recommendations of expert organizations and endorsed by agencies of the federal government responsible for health and safety. Therefore, there is no reason to believe that such towers could constitute a potential health hazard to nearby residents."

Some people have expressed concern that living, working, or going to school near a cell phone tower might increase the risk of cancer or other health problems.There are a small number of epidemiology studies that have shown brain cancer rates may be elevated in long-term / heavy cell phone users. However, the vast majority of scientific research to date does not support a link between Radio-Frequency (RF) energy exposure and human cancers. In theory, there are some important points that would argue against cellular phone towers being able to cause cancer.

First, the energy level of radiofrequency (RF) waves is relatively low, especially when compared with the types of radiation that are known to increase cancer risk, such as gamma rays, x-rays, and ultraviolet (UV) light. The energy of RF waves given off by cell phone towers is not enough to break chemical bonds in DNA molecules, which is how these stronger forms of radiation may lead to cancer.

A second issue has to do with wavelength. RF waves have long wavelengths, which can only be concentrated to about an inch or two in size. This makes it unlikely that the energy from RF waves could be concentrated enough to affect individual cells in the body.

Third, even if RF waves were somehow able to affect cells in the body at higher doses, the level of RF waves present at ground level is very low – well below the recommended limits. Levels of energy from RF waves near cell phone towers are not significantly different from the background levels of RF radiation in urban areas from other sources, such as radio and television broadcast stations.

For these reasons, most scientists agree that cell phone antennas or towers are unlikely to cause cancer.

I thank both of you for the answer. Recently I saw advertisements in Newspaper that cellphone tower radiation is not harmful to our health which is contrary to the popular belief. That is why I asked the question.

With best wishes,

Living near a cellphone tower might eventually melt your brain, give you cancer or worse, neuter your reproductive organs

Thus there is urgent need to take Precautionary Measures in order to avoid these harmful radiations entering in our body and causing biggest loss to your health. Following measurements are provided below for your attention :

– Wi-Fi Routers /Boosters should be placed at a distance.

– Switch off the Data Pack on mobile and Wi-Fi when not in use.

– While sleeping keep all the cordless devices at a safe distance from you

– Communicate through SMS as an alternate to calling.

– Use Wired Headsets for long conversations.

– Mobile Phones having ‘SAR’ value less than 1.6W/kg should be bought.

– Avoid placing mobile phones directly over pacemakers

– Keep distance – Hold the cell phone away from body to the extent possible

– Use a headset (or ear bud) to keep the handset farther from your head.

– Use a wired headset

– Limit the length of mobile calls.

– Use text as compared to voice wherever possible

– Put the cell phone on speaker mode- If the radio signal is weak, a mobile phone will increase its transmission power.

– Find a strong signal and avoid movement – Use your phone where reception is good.

– Metal & water are good conductors of radio waves so avoid using a mobile phone while wearing metal-framed glasses or having wet hair.

– Let the call connect before putting the handset on your ear or start speaking and listening – A mobile phone first makes the communication at higher power and then reduces power to an adequate level. more power is radiated during call connecting time

– If you have a choice, use a landline (wired) phone, not a mobile phone.

– When your phone is ON, don’t carry it in shirt or pant pocket. When a mobile phone is on, it automatically transmits at high power every one or two minutes to check (poll) the network.

– Reduce mobile phone use by children as a younger person will likely have a longer lifetime exposure to radiation from cell phones

– People having active medical implants should preferably keep the cell phone at least 15 cm away from the implant.

Best wishes
