Simulation results of gamma flux from the Californium source at the Lancaster University Neutron Source (LUNL), using MCNP 6. This data was used to benchmark the GPR approach used to interpolate radiation observations collected by an unmanned ground vehicle. Data is comma separated, with a header row. Columns are x, y, and z grid positions in centimetres, followed by the recorded flux and error estimate.Data was recorded for an xy plane, mimicking the height where a sensor affixed to a ground robot would sample. The flux is energy integrated over 200 keV to 2500 keV, similar to the CeBr3 detector used in robot deployment.The simulation environment consists of an isotropic 252Cf source surrounded by water, an air gap, followed by a concrete outer layer. Gamma flux contributions come from the source directly (spontaneous fission spectrum), as well as activation of nearby materials.
