A novel Si(Li)-NaI(Tl) spectrometer was developed for measurements of UL X-rays from /sup 239/Pu in the lungs of exposed persons. The spectrometer consists of six large, cooled Si(Li) detectors mounted on edge to provide two windows, one facing the lungs and the other a NaI(Tl) scintillator for anti...
