TABLE 2. Influence of 60-Hz vertical electric field, 100 kV/m, on development and variance in development in mice. The average value ± SD (in grams) are listed at the indicated number of days after birth. Values of mean weight and SD that differed significantly from the corresponding controls are indicated by an asterisk. N is given in parentheses. See R.D. Phillips, L.B. Anderson and W.T. Kaune: Biological Effects of High-Strength Electric Fields on Small Laboratory Animals, Richland, WA, Pacific Northwest Laboratories. DOE/TIC-10084, Contract E4-76-C-06-1830, 1979.
