All employees were employed for at least six months with some employment in the period 1973{\textendash}82. Computerised work histories were available for 79 972 study subjects for the period 1971{\textendash}93. Information on job and facility (location) were used to estimate exposures to magnetic fields. Two analytical approaches were used to evaluate risks, indirect standardisation (n = 83 997) and Poisson regression (n = 79 972).Results: Based on serial mortality rates for England and Wales, deaths from Alzheimer{\textquoteright}s disease and motor neuron disease were unexceptional. There was an excess of deaths from Parkinson{\textquoteright}s disease of borderline significance. No statistically significant trends were shown for risks of any of these diseases to increase with lifetime cumulative exposure to magnetic fields (RR per 10 μT-y: Alzheimer{\textquoteright}s disease 1.10 (95\% CI 0.90 to 1.33); motor neuron disease 1.06 (95\% CI 0.86 to 1.32); Parkinson{\textquoteright}s disease 0.88 (95\% CI 0.74 to 1.05))Conclusions: There is no convincing evidence that UK electricity generation and transmission workers have suffered increased risks from neurodegenerative diseases as a consequence of exposure to magnetic fields.}, issn = {1351-0711}, URL = {https://oem.bmj.com/content/64/12/820}, eprint = {https://oem.bmj.com/content/64/12/820.full.pdf}, journal = {Occupational and Environmental Medicine} }
