Response Characteristics of a Cylindrical Ionization Chamber to the Low- and Medium-Energy X-ray Beams

Abstract

The response of a cylindrical NE2571 ionization chamber to the low-and medium-energy X-ray beams was simulated using a Monte Carlo code PENELOPE. The simulation geometry of the cylindrical chamber was modeled as specified by the manufacturer. The ratio of the air kerma to the cavity dose of the chamber was calculated as a function of photon energy for the broad parallel beam incident normally to the cylindrical axis of the chamber. Results were compared with other experimental and theoretical works
