In this paper, the principle of gamma ray determination of the humidity of capillary hole objects is introduced. The γ-ray test bench and measurement technique are introduced. The dynamic and basic laws of wet conduction are analyzed. The formula to determine the difference of humidity and bulk density is deduced. Finally, the article lists the measured and measured results of humidity field and wet conductivity. The results of measuring the humidity with γ-ray were compared with the results of the sampling-drying method to measure the humidity. It was proved that the humidity field and the wet conductance of capillary hole objects could be determined without destroying the specimen.
