Study type: Epidemiological study (observational study)

Environmental power-frequency magnetic fields and suicide epidem.

Published in: Health Phys 1981; 41 (2): 267-277

Aim of study (acc. to author)

A study was conducted in the Midlands of England, UK, to determine whether there was a relationship between the act of suicide and the power-frequency magnetic fields at the domicile of the victim. The study is based on the study population of the publication by Reichmanis et al. (1979) with an improved exposure assessment by measuring the magnetic field strengths.

Results (acc. to author)

The magnetic field strength measurements ranged from 0.001 to 1.5 µT, with a mean of about 0,080 µT and a median of about 0,040 µT.
Significantly more suicides occurred at locations of high magnetic field strength. This effect could not be ascribed to different housing preferences among suicides as compared to the general population because no differences in geographical distribution or type of housing between the suicide and control addresses were observed.
