✦ Synopsis

The uncertainty in the activity determination of uranium contamination due to real inhomogeneous distribution and assumption of homogenous distribution can reach more than one order of magnitude when using one detector in a set of 4 detectors covering most of the whole lungs. Using the information from several detectors may improve the accuracy, as obtained by summing the responses from the 3 or 4 detectors. However, even with this improvement, the errors are still very large, up to almost a factor of 10 when the analysis is based on the 92 keV energy peak and up to 7 for the 185 keV peak.
