Bulk material analyzer assembly including structural beams containing radiation shielding material

An assembly of components for constructing a bulk material analyzer of the type that is used to analyze bulk material transported on a conveyor belt through an activation region located in a tunnel between at least one radiation source and at least one radiation detector within the bulk material analyzer, said assembly comprising:

• a radiation-source box for disposition either above the activation region or below the conveyor belt;
• a radiation-detector box for disposition either below or above the radiation source box on the opposite side of the activation region and the conveyor belt from the radiation-source box;
• and
• a set of stackable structural beams predominantly containing radiation shielding material and configured for stacking about the activation region, the radiation-source box and radiation-detector box to prevent unwanted radiation being generated and transported to the radiation-detector box when said boxes are disposed on opposite sides of the activation region and the conveyor belt from each other;
• wherein said assembly can be used to construct a bulk material analyzer that can be mounted directly on an existing conveyor support structure, without removing or substantially modifying any part of the existing conveyor support structure.
