Health Effects - Power-Line Frequency Electric and Magnetic Fields
Quoted from the NIEHS REPORT on Health Effects from Exposure to Power-Line Frequency Electric and Magnetic Fields. Prepared in Response to the 1992 Energy Policy Act (PL 102-486, Section 2118), NIH Publication No. 99-4493.
"The association between occupational exposure to ELF-EMF and Alzheimer's disease was considered in five studies (66-70). All five studies showed increases in one or more exposure groups with four studies (66-69) showing statistically significant increases....The one remaining study (70) was evaluatd using data for twins and also suffered many limitation. These data are inadequate for interpreting the possibility of an association."
"Changes in heart-rate variability were evaluated in a retrospective analysis of three previous studies
(77).
Some changes in heart-rate
variability were observed,
which according to the authors, could indi-
cate a potential for increased
risk of sudden cardiovascular death."
