Abstract
Gamma ray absorption techniques have been applied to measure the density of various media, and the theory of selecting the appropriate energy gamma ray to give optimum sensitivity of density determination for a homogeneous system is outlined. A gauge to determine the concentration of tungsten powder suspended in water in a concentration range of O to 8 gm. tungsten/c.c. suspension, has been developed. In this apparatus the mean tungsten concentration, 0.08 gm./c.c., can be measured to an accuracy of approximately +-0.0015gm./c.c. In the case of liquid sodium contained in o stainless steel vessel, preliminary experiments indicate that the density may be measured to an accuracy of +-0.01gm./ c.c. and that 0.01gm./c.c. transient changes in density occurring in a few seconds can be resolved.
