More than half of the publications in the internet report that there is no problem due to mobile towers and mobile phones. These are from the industry itself. Lot of publications gave alarming reports. Problems reported in literature as biological effects of radiation are : Sleeping disorder, Joint pain , dryness & flashing of eyes , Memory related problems , Fertility problems , cancer , reduction in immunity level and possibility of infections , diseases and quality of life.
International standards exists in erecting Mobile Phone Towers and standards also have guidelines for accepted power levels. Distance from residences , schools , hospitals etc are specified separately. India has adopted ICNIRP ( International Commission on Non - ionizing Radiation Protection ) standards. ICNIRP followed in the US and EU is the worst amongst the standards. Maximum power level as per ICNIRP is 9.2 watts / m2. ICNIRP is only intended to protect public against short term gross heating effects and NOT against ' biological ' effects such as reducing immunity level leading to infections to cancer and genetic damage from long term low level microwave exposure from mobile phones , masts and many wireless devices . But biological damage occurs at much lower rates. In a study conducted in Germany safe power density at any point is given as less than 100 microwatts / m2 . EU parliament ( STOA 2001 ) recommends - 100uW/m2. Russia has adopted .02 w/m2 and China .1 w/m2. They are considering to reduce further . DoT has reduced the safe radiation level as 450 milli watts / m2 after September 2013 considering the safety of people . But it is 4500 times more than the safe value !
Radiation density is inversely proportional to the square of distance from antenna. In US the safe distance is 500 meters. In India , only Himachal Pradesh has specified the distance as 100 meters away from homes. Kerala , West Bengal , Delhi , Mumbai , Odisha, Andhra Pradesh etc. does not have any specification on distance and a distance of 3 meters is taken based on existing rules for installing electric posts ! Measurement is the only way to find out radiation density at a place. The value can be the effect of all the towers nearby. A good radiation meter SRM 3000 used by industry costs Rs Fifteen lakhs. It is a compact , frequency selective measuring system for safely analysis and environmental measurements of high frequency electromagnetic fields. It has wide band antenna covering 9 KHz to 6 GHz. and provides radiation level at selected frequency spectrum . Prof Girish Kumar , IIT Mumbai has developed a low cost radiation meter Detex189 which has LED indication , green for safe level - 15dbm level. With the help of VSSC , we made measurements . The effect of Wi-Fi , Laptop , micro oven were also studied.
