title: Mathematical aspects of a rotating point source with an application to megavoltage shielding.
abstract: This study developed the mathematics of a rotating point source. The relative dose and the dose rate were numerically evaluated at various positions along the cardinal axes, both with and without a 1-m-thick concrete barrier. The point source model was compared to experimental data gathered at an operational megavoltage radiation therapy facility.
