title: Comparison of geometries for in vivo measurements of actinides in the skull.
abstract: In vivo measurement of actinide activity in the skeleton is a valuable source of information on human internal contamination. Estimates of skeleton activity are based on measurements of the knee, elbow or skull. Different laboratories use different measurement geometries. Different calibration phantoms and detectors are used, making a comparison of detection efficiencies rather difficult. This paper compares various head measurement geometries when using MC simulations with a voxel head phantom.
