One feature pertains to a radiation dosimeter comprising a microdosimeter cell array that includes a first microdosimeter cell having a first semiconductor volume configured to generate a first current in response to incident radiation. The first semiconductor volume may have at least one of a first size, a first shape, a first semiconductor type, and/or a first semiconductor doping type and concentration that is associated with a first biological cell type or a first biological cell component type. The dosimeter may further comprise a processing circuit communicatively coupled to the microdosimeter cell array and configured to generate a signal based on the first current. The signal generated may be indicative of an amount of radiation absorbed by the microdosimeter cell array. A display may be utilized by the dosimeter to show a radiation level reading based on the signal generated.
