ABSTRACT
Most biological components are diamagnetic or paramagnetic and only interact weakly with magnetic fields. For this reason, the effect of nonionizing radio frequency (RF) radiation in biology is commonly described in terms of heating.1 However, iron is an essential element to most living organisms, including, of course, humans. A healthy adult needs between 10 (males) and 18 mg (females) of iron per day, the highest concentration of any metallic element.2 Although it has a crucial role in biochemical mechanisms such as oxygen transport and redox processes, iron is also a potential toxic agent to cells via the Fenton reaction. Therefore, it requires a complex set of regulatory mechanisms to meet the demands of the body while avoiding accumulation or release in the wrong environment.3
