This article analyzed the relationship between sensitivity of a γ -ray density meter and the radiation source. All work was based on the numeric simulation by GEANT4 system. We conclude that a lower energy radiation source gives higher sensitivity
and the position and collimation characteristic of the source have little influence on sensitivity of the system.
