EMF example

An EMF is an electric and magnetic field produced by an electric current. These fields are formed around all appliances using electricity, around power plants generating electricity, as well as around power lines conducting electricity from one place to another.

Since the 1960s, studies have been conducted to investigate whether these EMFs have any effects on human health, particularly in terms of causing cancer. Most of the electric fields produced are shielded by intervening objects between the source of the field and people, so the health concern is focused mostly on the magnetic fields. Studies have shown mixed results in terms of statistical associations between exposure to EMFs and poor health outcomes. The potential biological mechanism by which EMFs would cause cancer or other health effects has not been determined, and no mechanisms are backed by biological evidence. Additionally, EMF exposure is difficult to measure. Currently, most scientists believe that the evidence does not indicate a high hazard in terms of health effects from EMFs. Some scientists and policy-makers stress the uncertainty factors, while others stress the lack of evidence indicating negative health effects (16).

Public concern and outrage, however, about dangers from EMFs is increasing. This may be because concern about EMFs is being lumped with concerns about radiation from cellular phones and cellular phone towers. This concern has predominantly been manifested in terms of power lines. Actions showing this concern and outrage include petitioning government to regulate the placement of power lines and protesting companies expanding their power distribution lines and building new generating stations.

Scientists say: "In the absence of evidence from cellular or animal studies, and given the methodological uncertainties and in may cases inconsistencies of the existing epidemiologic literature, there is no chronic disease for which an etiological [causal] relation to [power-frequency fields] can be regarded as established." -International Commission on Non-Ionizing Radiation Protection (16)

No wonder the public is concerned!
