Open the CIPO recordAbstract From the Canadian patent
The proportion of a radioactive material in a moving mass of material is determined with a sensor which derives an output signal proportional to the mass of radioactive material. The output signal is calibrated against known reference values to give a quantitative value of mass. The sensor includes a plurality of scintillation crystals. Problems associated with inhomogeneity of material distribution are overcome by averaging the sensed radiation over a time period.
