Abstract
Methods and apparatus for continuous real-time measurement of bulk material using gamma irradiation. A multi-energy gamma attenuation device monitors bulk material flow and produces a spectrum that is compared to a baseline spectrum to produce a relative weight/impurity/component ratio. A sample analysis, in combination with measurement of the relative weight/impurity/component ratio of the sample, allows for determination of the coefficients for determining the absolute weight/impurity/component values of the bulk material.
