Extra high voltage overhead lines at Indonesia
Electrical transmission tower Research and impact
- The study, which greatly affect the world community views about the relationship of cancer of the brain in children with exposure to electromagnetic fields is the result of research Wertheimer and flat in 1979 , which could shake the world because of the risk of negative reporting. Since that study, various studies of epidemiology and other laboratory performed as replication and eskpansi Wertheimer research in various countries. However, the results obtained would vary largely even contradictory. Reportedly, the study Feyching and Ahlboum, 1993, meta-analysis is the research that supports the results of Wertheimer, while the study of the National Cancer Institute (NCI) in 1997 in the United States, Canada Study, 1999 British study from 1999 to 2000 and the New Zealand study found results that do not support Wertheimer.
- A study conducted by Dr. Gerald Draper and colleagues from the Childhood Cancer Research Group at Oxford University and Dr. John Swanson , scientific adviser at National Grid Transco , found that children who live less than 200 meters of high voltage lines at birth have a risk of suffering from leukemia by 70 percent instead of living from a distance of 600 meters or more.Found five times more prevalent cases of leukemia in infants who were born in the area around SUTET or equal to 400 in a year than 1 percent of the population living in the area. Overall, the children whose lives within a radius of 200 meters of high voltage pole about 70 percent of them affected by leukemia and who lived between 200-600 meters in approximately 20 percent compared to those living more than 600 meters. Nevertheless, the increased risk of leukemia was found at a distance where the large electric field value under the conditions inside the house, so concluded that the increased risk of leukemia was not caused by an electric field or magnetic field caused by SUTET [1]
- PKK, the population at 500 kV EHV transmission lines in Pekalongan Regency , Regency Pemalang , and Tegal regency (2004) showed that the greater the risk of electrical sensitivity in the population residing in the 500 kV EHV transmission lines are 5.8 times more likely than people without residing at 500 kV EHV transmission lines. In general it can be concluded that exposure to electromagnetic fields from 500 kV EHV transmission lines at risk of causing health problems in the population, which is a set of symptoms known as electrical hypersensitivity sensitivity of headaches (headache), dizziness (dizziness), and chronic fatigue (chronic fatigue syndrome .) Anies findings concluded that these symptoms can be experienced all three at once by someone, so the discovery of this new discourse as " Trias Anies ".
- Corrie Wawolumaya from the Department of Community Medicine Faculty of Medicine, University of Indonesia has done research on the settlements around SUTET. H The results found no relationship between cancer and leukemia SUTET [2]
- John moulder trying to draw conclusions from hundreds of studies on the impact on health SUTET. Moulder concluded that no causal relationship between electric and stress field of human health (including cancer). However the voltage field has not been proven absolutely safe.In addition it also agreed that if any health hazards to humans, then it only occurs in a small group [3] .
- WHO concluded that not a lot of influence caused by the electric field to 20 kV / m in humans and electric fields up to 100 kV / m did not affect animal health. SIn addition, the experiment several volunteers at 5 mT magnetic field had little effect on the results of clinical trials and physical [4]
