Stockpile measurement calculator11/19/2023 ![]() Since the relationship between counts and density is dependent upon the atomic structure of the material being tested, however, these factory calibrations are prepared for maximum accuracy within a broad range of materials that it is expected the gauge will be used in. Normally, the gauge is provided with various graphs and/or charts prepared at the factory for the purpose of converting the count number to a density measure. The reading obtained represents a measurement of the number of nuclear back scattering events recorded by the gauge sensor, and this number of events must then be converted into a meaningful density measurement. The nuclear gauge utilized for density determination does not provide a signal that can be displayed directly as a density measurement on the scaler. The bulk of the density determination method is performed in the field at the stockpile site, and consists essentially of two stages.
