ABSTRACT:
A modular assembly for a bulk material includes container modules defining at least one radiation source cavity, at least one radiation detector channel and a passageway disposed for enabling passage of the conveyor belt through an activation region; and radiation shielding material disposed within the container means. A lower primary module contains a first portion of the radiation shielding material and defines either the radiation source cavity or the radiation detector channel. An upper primary module contains a second portion of radiation shielding material and defines the other of either the radiation source cavity or the radiation detector channel. A set of replaceable side modules contain additional portions of the radiation shielding material. The lower primary module, the upper primary module and the replaceable side modules are so shaped that the passageway is delimited by placement of side modules upon the lower primary module and placement of the upper primary module upon side modules; and portions of the replaceable side modules are shaped for delimiting the sides of a trough that is contoured for accommodating passage of the conveyor belt through the activation region. Replaceable liners of neutron moderating and/or absorbing and/or reflecting material may be placed adjacent the passageway and adjacent the side modules and/or the lower module and/or the upper module for further delimiting the passageway and/or the sides of the trough. The assembly can be modified for use with large ranges of conveyor belt sizes and shapes by replacing the replaceable side modules and/or the replaceable liners.
