The mushrooming of unauthorized colony due to population explosion in India poses a possible health hazards to people living nearby transmission towers, as RF radiation produces thermal effects and remained under their continuous influence for a long time can produces various health related problems. In this research paper, assessment of electromagnetic waves has been carried out by measuring the received field strength at different distances and has been compared with the available International standards. In order to execute this research work we have considered five All India Radio and Doordarshan stations located in Punjab and Jammu & Kashmir i.e. northern region of India. Chosen stations or sites are operating at different power level ranges from 100 W to 10000 W and transmitting the EM wave with different transmitting antenna heights i.e. from 45 m to 200 m. Field Strength measurement has been carried out by using the Anritsu Site Master and Anritsu make Antenna. In our findings, all the broadcasting stations sites found to be well within compliance limits set by International agencies but on increasing the receiving antenna height the received field strength in vicinity start to increase correspondingly. So due to this increase in received signal strength high rise building near the transmitting towers could pose some health hazards. Some warning sign near the transmitting site should be installed on the identified locations in order to educate people for possible effects and remedies.
