Patent ID: 8858888

Claim:
A radiation dosimeter comprising: a microdosimeter cell array including a first microdosimeter cell and a second microdosimeter cell, the first microdosimeter cell having a first semiconductor volume configured to generate a first current in response to incident radiation, the first semiconductor volume having a first size, a first shape, a first semiconductor type, and a first semiconductor doping concentration, the second microdosimeter cell having a second semiconductor volume configured to generate a second current in response to the incident radiation, the second semiconductor volume having a second size, a second shape, a second semiconductor type, and a second semiconductor doping concentration, and wherein at least one of the second size is different than the first size, the second shape is different than the first shape, the second semiconductor type is different than the first semiconductor type, and/or the second semiconductor doping concentration is different than the first semiconductor doping concentration; and a processing circuit communicatively coupled to the microdosimeter cell array and configured to generate a signal based on the first current and the second current, the signal indicative of an amount of radiation absorbed by the microdosimeter cell array.
