Effect of a pulsed magnetic field on AKR female mice offspring.
AKR mice were exposed to a 6 mT, 12 Hz or 460 Hz pulsed magnetic field for 30 minutes twice a week. The exposure took place in utero and/or during the life span for five consecutive generations. For the exposure the grown-up mice were put into a container which caused a restraint stress. That stress brought about lighter newborn mice and also a higher number of newborn mice which were to die. The exposure lessened the loss of weight due to the stress. It had no noticeable effect on the average numbers of newborn mice per litter, of dead newborn mice and on the sex-ratio.
