Abstract

Five methods of γ-ray self-absorption correction for bulk sample were investigated. It was clarified that there is no significant difference in quality among four methods, except for one method, while a few percents of discrepancy were observed in case of larger value of attenuation coefficient than 0.1 cm^-1. One of those methods is recommended for practical γ-ray spectrometry on account of the simple calculation method and no experimental data needed. Self-absorption for low energy γ-rays with high attenuation coefficient was a little dependent on Ge crystal diameter.
