Photonic Dosimeter and Process for Performing Dosimetry

NIST Inventors
Ronald Tosh, Zeeshan Ahmed, Ryan P. Fitzgerald and Nikolai Klimov
Patent Description Radiation-induced materials modification is ubiquitous. These applications rely on dosimetry to reliably deliver the desired amount of radiation to the right place. Currently the dosimetry standard is based on calorimetry of a large water phantom irradiated exclusively by Co-60
