Abstract: A detector including a resistance measuring device connected to a first conductive wire and a second conductive wire. The detector can be formed of a material that experiences Radiation Induced Conductivity (MC) when exposed to radiation and can be placed in a radiation field to measure electrical resistivity of the detector and the radiation field to gauge a strength of the radiation field. As the radiation field increases, the electrical resistivity of the detector decreases. Additionally, a combination detector can include a first detector with a first wire and a first material, and a second detector with a second wire coated with a coating comprising a fast or thermal neutron absorber. When placed in the thermal neutron field, the coating on the second detector removes a portion of thermal neutrons and leaves RIC effects on the second wire below the coating due to a remaining portion of thermal neutrons.
