text: Electromagnetic fields cause both ions and electrons to move about.  This can produce heat, damaging effects, or even severe injury depending on the strength and frequency of the EMFs.\n\nIons are very important to various physiological processes, same for electron transfer.  \n\nToo much heat damages cells.\n\nTime, distance, shielding and field intensity are important factors in limiting the damages.\n\nUnder certain circumstances EMF can slowly cook a person.\n\nThere are stories about Navy people using Target Acquisition (Fire Control) radars to cook seagulls in flight.\n\nNuclear radiation can affect the nuclei of atoms in addition to the effects for EMF.\n\nYes, EMF is a type of potentially harmful radiation.  Gamma rays and light are powerful varieties of EMF.\n\nEven weak or slow EMF at lower frequencies can sometimes produce headaches and disorientation.\n\nCows in pastures have been adversely affected from both overhead and underground power lines.\n\nDeath is possible.\n\nWe live in a sea of weak EMFs.  Strong exposures can occur from nearby antennas, especially those used for broadcasting or relaying communications via radio or microwave.\n\nThere are meters available for monitoring EMF intensities.\n\nThe ionosphere and ozone layers of the atmosphere protect us from damaging rays from space.\n\nTV cameras must be wrapped in aluminum foil in some bad EMF areas.\n\nI live in a mobile home, this affords some protection too.\n\nGenerally microwaves and other shorter, more powerful wavelengths are more damaging.\n\nSunburn is a form of EMF damage.  Similarly you can see in medical work burns from other types of EMF exposure.
