A method comprising the following steps: (a) adjusting a radiation dose measurement for a fluorescent nuclear track detector based on a plurality of fluorescence contrast images for the fluorescent nuclear track detector to thereby produce a calibrated radiation dose measurement, and (b) displaying the calibrated radiation dose measurement to a user and/or saving the calibrated radiation dose measurement to a storage medium, wherein the fluorescent nuclear track detector comprises a luminescent material, wherein the radiation dose measurement is based on one or more fluorescent light measurements produced by fluorescent imaging of the fluorescent nuclear track detector using excitation light from a laser having a first wavelength, and wherein the plurality of fluorescence contrast images are produced by illuminating the fluorescent nuclear track detector with excitation light having a second wavelength.
