Electric and magnetic fields

Electric and magnetic fields (EMFs) occur naturally and also as a result of the production of electricity. We are all constantly exposed to varying levels of EMFs but these fields are so weak they can't be felt. EMFs have a much lower frequency and energy than microwaves or X-rays, and do not have the same effects on the human body.

EMFs are strongest close to their source and drop off rapidly with distance. The scientific question of whether power frequency electric and magnetic fields cause diseases such as cancer still remains unresolved despite more than 20 years of international research. There is no conclusive evidence that electric and magnetic fields (EMFs) can cause biological changes related to the development of cancer.

However, until more information is available, customers may choose to limit exposure to EMFs in the home by increasing their distance from appliances when they are in operation. The electricity industry will continue to act prudently - any suggestion of a health risk, however weak, will be taken seriously and subjected to detailed scientific study.

At the national level, the Energy Networks Association (ENA) is working on behalf of the industry to monitor scientific developments and industry response.
