The following groups were examined: exposure to a 50 Hz field with 1) 1 mT, 2) 2 mT, 3) 3 mT, 4) 5 mT. Each group consisted of 3 petri dishes with 500 cells each for exposure and 3 petri dishes with 500 cells each as control group. One exposure dish and one control dish in each group were examined after 24, 48 and 72 hours, respectively. All experiments were repeated three times. The hypothesis was that conditions in groups 1 and 2 would lead to an increase in cell growth and conditions in groups 3 and 4 would lead to a decrease in cell growth. The background was the possible use in therapeutic treatments of skinlesions and skincancer.
three sets of coil pairs (distance 10 cm, separated by glass teflon) were made from polytetrafluoroethylene and placed next to each other in the same incubator
