In vivo measurement of actinides activity in human skull is a valuable technique of internal dosimetry. Many articles were published on calibrations and some new facts were found. The most important finding was that the relation of measured head size and size of a calibration phantom has notable effect on measured activity; however real impact depends on the detectors geometry. Still opened and never studied issue is: How variation in the head shape influences measured activity. Current study tries to provide answer to this question by the means of Monte Carlo simulation and voxel phantoms.
