Radiation is the emission or sending out of energy from any source. X-rays are an example of radiation, but so is the light that comes from the sun and the heat that is constantly coming off our bodies. When talking about radiation and cancer, many people think of specific kinds of radiation such as x-rays or the radiation in nuclear reactors. But these are not the only types of radiation that concern us when we think about radiation risks to human health.
If the answer to this question is yes, the chances are that you need to learn about EMFs quite quickly. The information on this page may be of use to you.
We hope that this page answers all your questions but should you find that you need more information on EMFs then you can discuss your specific questions with a professional EMF Advisor by contacting the EMF Helpline.
This page is about overhead lines — see the parallel page on living near a substation EMFs are all around us Electric and magnetic fields are produced wherever electricity is used — they are around us all the time in modern life.
Overhead power lines — specifically, the wires, not the pylons that hold them up — are a source but they are only one source. More on where exposure comes from Electric fields are produced by voltage and magnetic fields by current. Where there are concerns, they are mainly about magnetic fields.
We also get short-duration higher field exposures when we pass close to electrical appliances. Outside the home, we can experience EMFs in schools, factories, offices, when using electrified transport, and when we are out shopping.
But for those who do, this will also be a significant source of exposure. In homes not near power lines, the magnetic field in the general volume of the home can range anywhere from 0.
This will usually come from the wiring along the street that supplies electricity to the home. The field usually drops off to the 0. Over the last 40 years there have been suggestions that magnetic fields, at the levels produced by overhead lines, may cause diseases, principally childhood leukaemia.
More on these suggestions The evidence for this comes from epidemiology studies the study of statistics about diseasewhich have found a statistical association — an apparent two-fold increase in leukaemia incidence, from about 1 in 24, per year up to 1 in 12, per year, for the children with the top half-percent of exposures.
So overall the science is uncertain. Because these studies only show statistical associations and do not demonstrate causation, and because the evidence from the laboratory biology and theoretical science is against, the risk is not established, it remains only a possibility. It really established the idea that there is a statistical association with fields above 0.
There have been other pooled analyses since which have mainly reinforced this finding. It found an association — but one that extended too far from the lines to be attributable to magnetic fields, and which declined over the decades from the s to the present.
This suggests that whatever is going on, it may not be magnetic fields. And there seems to be no association in the last couple of decades. The statistical associations from the epidemiology studies seem to show up at fields above 0.
Sometimes people talk about 0. How many UK homes does this apply to? The great majority of homes in the UK have fields less than these values. These percentages of homes with higher fields are actually smaller than in many other countries. Only about a half of homes in the UK with fields above 0.
But if you do live close enough to an overhead line, that will give you a higher exposure. The limits are designed to prevent all established effects of fields on the body. More on policy and exposure limits in the UK Policy and exposure limits are ultimately set by the Government.Living Close to Power Lines.
Power lines carry high-voltage electric current from one place to another. When current flows through a wire, two fields are created around it: an electric field and a magnetic field.
These are the two components of the electromagnetic field. Health Effects of Living Near Power Lines – Is EMF Really Harmful? Electromagnetic fields (EMF) and health issues The effect of electromagetic fields (EMF) from power lines and other sources is a controversial issue Legionnaires' disease.
Buying, selling or living near an overhead line. In homes not near power lines, the magnetic field in the general volume of the home can range anywhere from µT to µT. The limits are designed to prevent all established effects of fields on the body. Over the past 30 years, scientists have published close to 25, articles on the health effects of non-ionizing radiation (the kind emitted by power lines).
We’ve had population, occupational, and laboratory studies scrutinizing everything from high-voltage transmission lines to electric blankets. Low- to mid-frequency EMFs, which include static fields (electric or magnetic fields that do not vary with time), magnetic fields from electric power lines and appliances, radio waves, microwaves, infrared radiation, and visible light.
Feb 17, · The effect of these electrostatic fields is seen prominent with living things like humans, plants, animals along with vehicles, fences & buried pipes under & close to these lines.
