摘要：
An apparatus and method for triaging patients according to radiation exposure operates by measuring electron paramagnetic resonance spectra of fingernails, toenails, and/or teeth. When operating in vivo, radiation induced spectra are obtained from intact fingernails, toenails, or teeth placed within a magnet and with pickup coils located over nails between the cut edge at the end of the fingernail and skin proximal to the nail or placed adjacent to at least one tooth. When operating in vitro with fingernail clippings, one or more spectra are obtained. In an embodiment, at least three spectra are obtained with at least one after a delay at above twenty degrees Celsius, and at least one at power levels different from the others. The three spectra are used to determine and remove a mechanically induced signal from EPR spectra to determine radiation-induced spectra. The radiation induced spectra are used to determine a radiation dose, the dose is compared to triage limits, and a radiological triage tag is printed for the patients.
