The waves in the magnetic field used by the HST researchers have the same frequency range as radio waves (between 350 and 400 kilohertz). These waves pass harmlessly through the body and heat only the nanoparticles. In comparison, microwaves, which would cook tissue, are about a million times more powerful with frequencies measured in the gigahertz range.
