WHO has prescribed restriction of potential harmful level of electromagnetic energy
Thousands of people living near high-voltage power lines may have been exposed to an electromagnetic radiation that is likely put them at possible health risk. However, the authorities appear to be apparently unconcerned about the effects of living close to those power lines. “We have houses and businesses right under the electric wires where many people even sleep at night without any problem,” claimed a highly-placed source.
In an exclusive interview to The Independent at his office on Thursday, Jamal Ullah, managing director of the Power Grid Company of Bangladesh, said: “We do not have any information on any danger ever posed by the high-voltage power lines to human health.” Bangladesh has already come under a cross-country network of 9,000 km of high-tension power lines covering virtually all places. Roughly 10 per cent or 900 km of electric wires run directly over human habitations. “We’ve tried to keep the power lines directly over people’s residences and businesses at a bare minimum,” said Jamal Ullah, who was a member of the Power Development Board (PDB) for some time and has served in several senior positions in the energy sector for 34 years. The electromagnetic radiation, also called electromagnetic fields (EMF), comes from the high-voltage power lines and their structures. While a debate over the issue is on, the World Health Organization (WHO) has prescribed restriction of potential harmful level of electromagnetic energy under national and international guidelines.
Living near high-tension electric wires is safe if somebody`s home is far enough from these wires. However, a study carried out by the prestigious Oxford University`s Childhood Cancer Research Group in 2005 found that children living within 220
yards of an overhead power line had a 70 per cent greater risk of getting leukaemia.
Being alarmed by the increasing concern over the risk of children living close to power lines, the Environmental Protection Agency (EPA) of the
United States consulted with the U.S. National Institute of Environmental Health Sciences and concluded in 1998 that the power line magnetic fields are a possible source of cancer.
In addition to the possibility of developing childhood leukaemia, living close to high-voltage electric wires may also trigger a series of other health problems. In 2002, 2005 and 2006, the University of Bristol conducted three major surveys on the town of Stoke-on-Trent and found a higher rate of depression, headache and insomnia among people living near high-tension power lines.
Another serious health risk of living in close proximity to those electric wires is greater chances of miscarriages. The Stoke-on-Trent surveys reported 35 cases of miscarriages in areas near high-voltage power lines, compared to just two such cases in places further away from those power lines
Studies have also looked into a possible link between brain cancer, breast cancer, leukaemia and certain lymphomas in adults living near those wires, but have found conflicting results. Studies that found people living close to power lines were more vulnerable to cancer failed to take into account other factors, such as, genetics, nutrition etc. contributing to such illnesses.
High-voltage power lines used for transmission of electricity are quite common across the world, including advanced nations.
Many countries, including the U.S., U.K., Canada and Australia, have carried out extensive research on the effects of living in close proximity to power lines. So have neighbouring India and Pakistan, but a Google search for a similar research in Bangladesh came out negative.
Like in Bangladesh, thousands of people in India and Pakistan live near high-voltage power lines without knowing the dangers they may pose to their health. In Pakistan, Karachi University conducted a research on plants and found that the electromagnetic fields (EMF) significantly affected the genetic materials of those plants that grew directly under high-voltage power lines.
Even though several authentic studies conclude that electromagnetic fields are a “possible“ cause of cancer, utility companies continue to claim that living near high-voltage electricity transmission lines is safe. Experts suggest the safest thing to do is to avoid exposure to high-tension power lines and if one must live close to them, they should do so at least 600 yards away as suggested by the study of Oxford University.
