Radiation Survey Process

摘要

A method for determining a radionuclide concentration of a material is provided. The method comprises placing the material to be analyzed into a vessel, wherein the material comprises a radionuclide, wherein the material has a known volume, and wherein the vessel has a fixed geometry. The method further comprises weighing the material to be analyzed and measuring the moisture content of the material to be analyzed. The method additionally comprises placing a protective structure in the material and placing a detector in the protective structure, wherein the detector is coupled to a single-channel analyzer. The method also comprises counting the emitted radiation having a known energy over an interval of time to produce a count per time, wherein the emitted radiation is emitted from the radionuclide and then dividing the count per time by the weight of the material to produce a count per time per weight.
