    摘要： A method and apparatus for accurately locating and roughly identifying a radioactive uranium and/or transuranium isotope deposited in a wound, by monitoring alpha radiation in the edge region of the wound and at the wound surface to determine whether surface contamination is present, monitoring low-energy X-ray or gamma radiation at the wound to determine the presence of a low-energy X-ray or gamma radiation source, measuring the low-energy X-ray or gamma radiation in the wound by means of a succession of detectors having progressively increasing local resolution and progressively decreasing limitation of the detectable volume to effect coarse and then fine localization of even small isotope deposits. An isotope can be roughly identified by displaying the measuring result produced by at least one of the detectors as a pulse amplitude spectrum, and comparing the displayed result with subsequently measured spectra of predetermined isotopes.
