Filed: 1990-04-06
Abstract: PURPOSE:To obtain a level density meter for performing accurate measurement without errors by containing two kinds of gamma-ray sources for discharging the different gamma-ray energies in a shielded container, and discriminating and counting the energies by wave-crest discrimination with one detector. CONSTITUTION:Heat sources 1a and 1b are contained in a shielded container 2 and emit gamma-rays on a material to be measured 7 at a constant emitting angle. A gamma-ray detector 3 outputs a pulse wave crest which is proportional to the detected gamma-ray energy and sends the output into wave-crest discriminators 8a and 8b. In an operating device 5, the level and the density of the material to be measured 7 are operated and outputted based on the outputs of the discriminators 8a and 8b and preset measuring conditions. Thus, the level and the density can be measured at the same time with one shielded container and one detector. Since the gamma-ray paths are approximately the same, the level density meter which can perform the accurate measurement without errors can be obtained.
