Residents in northwest Delhi's Shalimar Bagh are demanding the demolition of a mobile phone tower in the residential area, alleging that electromagnetic radiation from it poses a threat to their lives.
Shubash Kapoor, a resident of BC Block in Shalimar Bagh (East), told IANS that an Idea Cellular tower has been erected on the terrace of the third floor apartment where he lives as a tenant, with the permission of the landlord.
As telecom giants pay huge rents, house owners allow them to set up mobile phone towers. "Why can't they look at other alternatives for revenue? Why are they playing with the lives of residents?" Kapoor asked.
"For over two years since the erection of the mobile tower, we have been suffering health problems like headache, fatigue and vomiting because of radiation. My six-year-old son is the worst-hit," she claimed.
"My doctor has confirmed these health issues are linked to radiation from the mobile tower," she added.
Sharma said their neighbour was suffering from cancer in the spinal cord, while another resident had complained of heart ailments.
According to the Municipal Corporation of Delhi (MCD), Delhi has over 5,000 mobile phone towers, of which 2,500 are illegally erected. Shockingly, most of these are in residential areas.
The MCD has threatened to seal illegal mobile phone towers because of possible health hazards. The Delhi High Court, which had earlier ordered the formation of a panel to study the health risks caused by mobile phone towers, put a stay on it and issued notice to the cellular operators association to file their responses by July 8.
"Despite the civic body's norms, many mobile towers are installed near residential colonies, schools, hospitals and dispensaries - all areas where they are not allowed," a civic body official told IANS.
Experts say mobile phone towers installed on top of buildings are a definite threat to human health.
"Exposure to electromagnetic waves generate heat in the body and high levels of radiation can even affect the enzyme system, cause mutation of DNA, protein structure and cell membranes," said Neha Kumar, an expert in industrial biotechnology, who has done research work on electromagnetic radiation.
"People who stay within the beam of the towers are the worst-hit. The continuous exposure to electromagnetic radiation could have a pernicious effect on our health," she said.
"The safest radiation exposure limit for a human being is 100 micro watts per square metre. But in many residential areas, the exposure limit is more than 1,000 micro watts per square metres," she added.
G.K. Jadhav, senior consultant in the oncology department of Apollo Hospital, said the worst-affected by mobile tower radiations are heart patients, particularly those who have pacemakers.
"We also attend to many brain tumour patients who are constantly exposed to electromagnetic radiation," Jadhav added.
However, chief co-operative affairs officer of Idea Cellular Rajat Mukarji denied the allegations, saying the towers installed by the company across the country are not harmful.
"The radiation levels are checked by a telecom engineering centre and they are at nominal levels; yet if the residents demand that the tower be removed, they should approach the company directly," he added.
The Telecom Regulatory Authority of India (TRAI), along with other central agencies, has proposed that the radiation exposure be limited to be 9.2 watts per square metre in India, though experts say this needs to be widely debated and analysed before implementation.
In some countries, the permissible limit in a radius between 50 and 300 metres varies from 0.001 to 0.24 watts per square metre.
"The level suggested in India is many times higher than that in the US, Switzerland, Poland and Russia," Kumar said.
S. Raghunath, senior scientist in the Central Electronics Engineering Research Institute (CEERI) at Pilani, however, said: "As a scientist, I cannot believe that mobile towers emit such radiation. Radiation from mobile phones used for long duration is higher than those from mobile towers."
