In vivo measurement of actinides in the human lung. [Calibration and comparison of Phoswich, large-area proportional counter, and intrinsic germanium planar array detector systems]
The problems associated with the in vivo detection and measurement of actinides in the human lung are discussed together with various measurement systems currently in use. In particular, the methods and calibration procedures employed at the Lawrence Livermore Laboratory, namely, the use of twin Phoswich detectors and a new, more realistic, tissue-equivalent phantom, are described. Methods for the measurement of chest-wall thickness, fat content, and normal human background counts are also discussed. Detection-efficiency values and minimum detectable activity estimates are given for three common actinides, /sup 238/Pu, /sup 239/Pu, and /sup 241/Am.
