Radiation dosimeters only measure ionizing radiation. The key thing to
remember is that nearly all devices that emit radio wireless in the safe
part of the EM spectrum - even those with a low current - still create a
small amount of ionizing radiation (usually very small, and insignificant).
If you are curious, I'd recommend spending $15 and perform the experiment I
outlined. My guess is that you'll likely have results that are very
comparable to mine, and as an added bonus, a cool party trick too! :-)
