Effect of a 12 Hz and of a 460 Hz pulsed magnetic field on the weight of AKR mice.
AKR mice were exposed to a 6 mT, 12 Hz or 460 Hz pulsed magnetic field (PMF) 30 minutes twice a week. The exposure took place in utero and/or during the life span for four consecutive generations. The adult mice exposed to the 460 Hz PMF only after the birth time were lighter than the controls; for the two frequencies the decrease in weight with the ageing was less pronounced than in the controls. When the exposure took place in utero the exposed new-born mice were heavier than the controls. The difference in weight progressively disappeared when the mice were exposed to the 12 Hz PMF, persisted when the mice were exposed to the 460 Hz PMF.
