Neutron Fluence and Dose from a Varian Clinic 1800 Accelerator

Abstract:

The goals of this study were 1 to verify calibration factors determined by previous experiment for relating counts from activated gold foils to neutron fluences, and 2 to use the method to determine neutron fluences under various operating conditions of the Varian Clinac 1800 18-MeV electron accelerator at the WPAFB Medical Center. For comparison similar measurements were made of the CGM Saturne 1 at Kettering Memorial Hospital, Dayton, Ohio. Cadmium-difference pairs in a standard graphite pile were employed to verify the counting efficiency of the Geiger-Mueller beta counting system used to count the foil activity. They were also used to determine the relation between the thickness of the gold foils and the activity induced in the foil self shielding and self absorption.
