Changes in Sodium and Potassium Content of Urine from Mice Subjected to Intense Magnetic Fields

  • G. D. Hanneman


Man is being exposed to increasingly higher magnetic fields on earth. Such exposures occur in plasma and solid state physics laboratories, industrial factories using magnetic forming devices, and other engineering disciplines. Betatrons and cyclotrons with magnetic fields ranging to 20 kOe are used for accelerating charged particles. It is reasonable to expect that in the near future man will be exposed to an increasing number of sources of even higher intensities. Magnetic fields to shield men against damaging radiation during extended space flights are contemplated.
