Low-Frequency Magnetic Fields in Cars and Office Premises and the Geomagnetic Field Variations.

abstract：:Both positive and negative biological effects of microwaves on drug actions in rats exposed to 1-mW/cm2, 2,450-MHz microwaves have been reported by several investigators. We conducted dosimetry studies for seven different exposure conditions to determine whether these different results could be due to the rats having ...
