WebMagnetic resonance imaging (MRI) uses radiofrequency (RF) radiation which is, again, different from light, lasers or ultrasound. The biological effects are different as well as the quantities used for measurement, i.e., power, and specific absorption rate (SAR). Negatively charged ions are produced when a free electron collides with an atom and is subsequently trapped inside the electric potential barrier, releasing any excess energy. The process is known as electron capture ionization. Positively charged ions are produced by transferring an amount of energy to a bound electron in a collision with charged particles (e.g. ions, electrons or positrons) or with photons. The threshold …
