1. A wearable device comprising:

  • a first microdosimeter cell array including at least a first microdosimeter cell and a second microdosimeter cell, the first microdosimeter cell having a first semiconductor volume adapted to generate a first current in response to incident radiation, the first semiconductor volume having at least one of(a) a first size approximating a size of a human eye cell,(b) a first shape approximating a shape of the human eye cell,(c) a first semiconductor doping type and concentration having an electrical conductivity that approximates an electrical conductivity of the human eye cell, and/or(d) a first semiconductor type having a linear energy transfer (LET) value for a first type of radiation that approximates an LET value of the human eye cell for the first type of radiation,the second microdosimeter cell having a second semiconductor volume adapted to generate a second current in response to the incident radiation, the second semiconductor volume having at least one of(e) a second size approximating a size of a biological cell or cell component,(f) a second shape approximating a shape of the biological cell or cell component,(g) a second semiconductor doping type and concentration having an electrical conductivity that approximates an electrical conductivity of the biological cell or cell component, and/or(h) a second semiconductor type having an LET value for the first type of radiation that approximates an LET value of the biological cell or cell component for the first type of radiation, andwherein the biological cell or cell component is different than the human eye cell and 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 type and concentration is different than the first semiconductor doping type and concentration; and

    a processing circuit communicatively coupled to the first microdosimeter cell array and adapted to generate a first signal based on the first current and the second current generated by the first and second semiconductor volumes, the first signal indicative of an amount of radiation absorbed by the first microdosimeter cell array.
