Abstract
A special type of free air ionization chamber is described; it was used for investigations on the French exposure dose standard. This new chamber enables ionization measurements to be made when the length of the measuring electrode tends toward zero. The various correction factors used in the absolute determination of exposure doses were measured using the chamber described, especially air attenuation, electric field distortions, influence of contact potential and scattered photons.Keywords
