Abstract
The recombination correction for a small cylindrical ionization chamber exposed to pulsed radiation is reexamined in the light of new experimental evidence. A simple two-voltage testing technique is described and demonstrated. In general the existing theory for an air-filled chamber (Boag 1950) is found to be accurate over the range of charge densities examined (0.013 p/pulse to 3.8 p/pulse) where p=3.33 X 10(-4)C. m-3 (1 esu cm-3).
