| 1. A method for determining the amount of ionizing radiation dosage received by a target, comprising the steps of:
placing a scintillator nanomaterial adjacent to a target, wherein the scintillator nanomaterial has a luminescent response
to ionizing radiation that varies with the ionizing radiation dosage received;
detecting the luminescence generated by the scintillator nanomaterial, wherein the luminescence is generated in the absence
of one or more secondary excitation sources, the one or more secondary excitation sources being selected from the group consisting
of thermal and optical excitation sources;
analyzing the detected luminescence in order to determine the ionizing radiation dosage received by the target.
