Efficiency modeling for neutron detectors
Neutron detectors are used for various applications, such as for workplace monitoring in a neutron field, during nuclear incidents, and for the detection of contraband nuclear material. The Remote Sensing Laboratory has developed and employed several neutron detector designs, and characterization data have been collected with these detectors under varying environmental conditions. Using MCNP/MCNPX the neutron fluence rate and dose rate were evaluated during open-field deployment as a function of moisture content in air and soil, barometric pressure, and varying pavement and soil composition.
