Abstract: The invention is the novel use of Quantum Dots (QDs) for radiation dosimetry and includes novel dosimetry devices, systems and methods. The devices, systems and methods have use in a variety of dosimetry applications such as personal, environmental and research. The system for detecting doses of ionizing radiation comprises; a matrix comprising a photoluminescent semiconductor nanocrystals; an illumination interface for exposing the matrix to non-ionizing radiation; a response characterization interface for measuring photoluminescence, scatter or the optical density of the matrix and identifying differences in the photoluminescence, scatter or optical density caused by exposure to ionizing radiation; and a readout interface to quantify the photoluminescence or optical density differences as doses of radiation.
