摘要:
ABSTRACTSIn the neutron activation analysis of museum specimens, for which sampling is not permitted, corrections must be applied to measured activities to take into account the sample shape and its position relative to the detector. Correction factors are derived for samples of cylindrical shape such as segmented faience beads and a model technique is suggested for those of irregular shape such as flint and obsidian implements. These techniques used in gamma‐ray spectrometry with lithium‐drifted germanium detectors enable elemental concentrations to be determined from the measured count ra
