Abstract
A series of dosimetric measurements was carried out using a Philips d + T generator, which produced neutrons with energies of .apprx. 14 MeV used in human radiotherapy. A-150 plastic ionization chambers, an A-150 plastic calorimeter, and a GM [Geiger-Mueller] dosimeter were used to determine total absorbed dose and the photon-absorbed dose fraction. The ion chambers were calibrated in a 60Co .gamma.-ray field in air and compared in a phantom placed in the 60Co .gamma.-ray beam. The total absorbed dose derived from the ionization chamber measurements was compared to that determined using the calorimeter. The neutron measurements between the techniques corresponded to within .+-. 2%.Keywords
