Abstract
The density of a mass of material is determined by passing radiation from a source, such as Co-60, whose radiation spectrum has a characteristic energy level above 700 keV through the mass of material to a detector that can detect radiation at a energy level, or range of energy levels, within the range 80 to 700 keV. By determining the density of the mass of material at different locations, the density profile of the mass of material can be assessed.
