ELF electromagnetic fields and neurodegenerative disease. Report of an Advisory Group on Non-ionising radiation

There are continuing concerns about the possible health effects that may arise as a consequence of exposure to electromagnetic fields and radiations (EMFs). In relation to exposures to power frequency (extremely low frequency, ELF) electromagnetic fields, the principal concern has been the possibility that they may be implicated in the development of cancer. In developing its advice for the Board of NRPB on the possible health effects of electromagnetic fields, the Advisory Group has reviewed a number of studies that have examined associations between Alzheimer's disease, motor neuron disease and Parkinson's disease and exposure to electromagnetic fields. These diseases may be classed as neurodegenerative disease as all involve the death of neurons, although their aetiology is different. This report examines first the biological basis of these neurodegenerative diseases, the location of the nerve cells implicated in their development, and the pathological changes that become manifest as they develop. lt then reviews the relevant epidemiological studies. These have examined the possibility of a relationship with exposure to ELF electromagnetic fields, particularly as a consequence of work involving the use of electricity (eg electric power line/cable workers, welders, electricians and dressmakers)
