Abstract

Considerable errors in the determination of radioactive contamination in lungs can be induced if there is no homogeneous distribution, as assumed for the calibration. Modern lung counter systems use several detectors, and the count rate ratios of the detectors can be used for localization of the radioactive contamination, enabling the use of correction algorithms. This greatly reduces the errors in the determination of the activity. Further reduction of the errors can be obtained by simultaneous analysis of several gamma lines (if several energies are emitted by the radioisotope), and by optimizing the number and location of the detectors. This presentation deals with the case of a point source of natural uranium in human lungs.
