Comparison study of ambient electromagnetic transients in the indian domestic scenario

The highest magnetic flux densities to which most people are exposed arise close to domestic appliances. Several epidemiological studies have reported an association between prolonged exposure to power frequency magnetic fields greater than 4 mG and an increased risk of childhood leukemia. In this paper we have shown the elf emf in Indian domestic scenario is very much low compared to developed nations. The best estimate of the geometric means of long- term average background fields in the United States is 60-70 nT and in the United Kingdom approximately 36-39 nT. In other countries, there are insufficient studies to draw firm conclusions on average fields. Measurements of personal exposure are higher than measurements of background fields, perhaps because they include exposures from appliances and other sources in the home. The study, commissioned by the National Radiological Protection Board (NRPB) UK concluded that one in 200 British children are exposed to high levels of electromagnetic radiation in the home and that this could be doubling their risk of leukemia.
