From third Health Physics Society midyear topical symposium; Los Angeles, California, USA (29 Jan 1969). See CONF-690103P1. Neutron energy spectra were obtained near the Yale M. P. Tandem Van de Graff Accelerator during scattering experiments. Spectral measurements were performed using a Bonner- Spectrometer with 2, 3, 5, 8, 10 and 12 inch spheres with protons and deuterons as the accelerated particles. Neutron spectra were measured for various beam currents for a given beam energy and projectile. The most recent set of dose conversion factors was used in converting these measured energy spectra into a total absorbed dose and dose equivalent. The results obtained were then compared as to total neutron yield, total absorbed dose, and total dose equivalent. From the dose information average quality factors were calculated and compared. Extensive data were accumulated at one location near the accelerator and this information is presented in such a form as to allow for the rapid determination of the dose equivalent rate by knowing various machine parameters.
