Abstract

See full text

Information on radiation dosage from segmented ionization chambers can be incomplete due to the existence of insensitive regions of the chamber. By measuring the total current to the high voltage power supply, the total ionization current including that in the insensitive areas can be estimated, thereby providing a measure of the dosage to the insensitive areas.
