Research Abstract

The large capacity parallel plate ionization chamber was made, and the operation evaluation was done under various conditions. The result of the average absorbed dose in the parallel plate ionization chamber and Farmer type ionization chamber that usually used it reached an almost equal value. It became an almost equal value in case of the IMRT radiation field. The absorbed dose in the field where the large capacity parallel plate ionization chamber was used can be measured, and there is a possibility of becoming one of the IMRT absorbed dose evaluations.
