Exposure of Mice to a Strong AC Electric Field - An Experimental Study

Twenty-two male mice were exposed to a 60-Hz ac electric field by placing them, in cages, between parallel plates energized to create a field, initially unperturbed, of 4 kV/in. In the course of 10½ months, each animal had an accumulated exposure time of nearly 1500 hours. These animals, and a parallel control group (essentially identically handled but receiving no exposure to electric fields), were repeatedly bred and observed to determine whether there were any effects, harmful or beneficial, as a result of the exposure.
