Electricity workers not at risk

Electricity workers don't face an increased cancer threat from low-frequency electromagnetic fields, says a Danish study that looked at the health and employment records of 28,000 electricity supply company workers dating back to 1968.

The researchers compared cancer rates among the workers to rates in the general population and concluded that exposure to low-frequency electromagnetic fields did not increase the risk of brain cancer, breast cancer, or leukemia, Agence France Presse reported.

The study findings contradict some previous lab studies that did suggest an increased cancer risk.

The study authors said their results indicate that there is no need to tighten international safety guidelines on occupational exposure to low-frequency magnetic fields, which have a frequency of 50-60 Herz, AFP reported.

The study was published in the journal Occupational and Environmental Medicine.
