Undergrad Earth's Magnetic Field vs Cell Phone EMF
If the Earth's magnetic field as measured on the surface of the Earth is somewhere between .3 and .6G and cell phone doses are around 2mG, is it then absurd to be at all concerned with even heavy exposures to the kind of low grade doses that cell phones and other electrical devices produce?
