While cell phone radiation is technically in the non-ionizing’ radiation category, to be clear there is not a perfect cut off for what is ionizing and what is not – it is a bell curve, AND importantly, depends on what the substrate (the substance is that the radiation is passing through). So for example even radiation that is considered to be ‘ionizing’ cannot ionize some substrates, while radiation that is generally considered ‘non-ionizing’ can ionize some substrates. Herein is a problem – the cells of the body contain thousands of substrates, many that are going to be quite susceptible to ionization from weak, low level non-ionizing radiation. However the one-size fits all government issued standards that regulate the industry (or more correctly that the industry regulates) are not adequate to the task of keeping people safe. As always, buyer beware.
