title: Derivation of a simple relationship between pulsed and steady-state dose limits due to general recombination within air-filled ionization chambers.
abstract: This paper discusses various calculational and measurement methods involved with general recombination losses of air-filled ionization chambers exposed to either steady-state or pulsed photon fields. Derived therefrom is a simple relationship between the pulsed and steady-state cases that allows the determination of expected pulsed-field losses from steady-state loss measurements within, for instance, typical Cs calibration fields. Several examples are provided to illustrate each calculational and measurement method, as well as the newly derived relationship.
