文摘

A MCNP6 model of a Hopewell Designs 137Cs irradiator was created and validated. Energy spectra variations from air-kerma modulation techniques were determined. The mean energy of the spectrum increased as lead attenuator thickness increased. The mean energy did not vary with the distance from the source for all attenuators. Room scatter from vault walls did not affect the mean energy for all attenuators.
