No increased risk of Alzheimer's, Parkinson's, or motor neurone disease found in electricity workers despite decades of elevated magnetic field exposure.

Plain English Summary

Summary written for general audiences

Researchers followed over 73,000 UK electricity workers for nearly 40 years to see if workplace magnetic field exposure increased their risk of developing Alzheimer's disease, Parkinson's disease, or motor neurone disease. They found no statistically significant increase in any of these neurodegenerative diseases, even among workers with the highest magnetic field exposures. This suggests that occupational magnetic field exposure at the levels experienced by electricity workers does not elevate the risk of these brain diseases.

Study Details

To investigate whether risks of Alzheimer’s, motor neurone or Parkinson’s disease are related to occupational exposure to magnetic fields.

The mortality experienced by a cohort of 73051 employees of the former Central Electricity Generatin...

No statistically significant trends were shown for risks of any of these diseases to increase with e...

There is no convincing evidence that UK electricity generation and transmission workers have suffered elevated risks from neurodegenerative diseases as a consequence of exposure to magnetic fields.

Quick Questions About This Study

A major 2014 study following over 73,000 UK electricity workers for nearly 40 years found no increased risk of Alzheimer's disease from workplace magnetic field exposure. Even workers with the highest exposures showed no statistically significant increase in neurodegenerative diseases.
Research on UK electricity workers exposed to power line magnetic fields for decades found no convincing evidence of elevated brain disease risks. The study tracked over 73,000 workers and found no significant increase in Alzheimer's, Parkinson's, or motor neurone disease.
A comprehensive 2014 study of electricity workers found no statistically significant link between magnetic field exposure and Parkinson's disease risk. Researchers followed over 73,000 workers for nearly 40 years, including those with the highest occupational EMF exposures.
The largest long-term study of magnetic field exposure and brain health found no convincing evidence of neurological risks. UK researchers tracked 73,000 electricity workers for decades and found no increased rates of Alzheimer's, Parkinson's, or motor neurone disease.
A major occupational health study found no evidence that working around electrical equipment increases brain disease risk. Researchers followed over 73,000 UK electricity workers for nearly 40 years and found no significant increase in neurodegenerative diseases from magnetic field exposure.
