Description
The past year has been devoted entirely to the evaluation of lineal energy spectra measured in the d(16) and p(66) fast neutron beams generated at Pretoria and Faure. An intercomparison study revealed good agreement with microdosimetric parameters determined at similar centres. The proportional counter measurements were futher exploited to evaluate the photon fraction in the mixed n/γ radiation fields. A microdosimetric assessment of beam quality was of particular value in determinig the optimum thickness of a beam-hardening filter for the p(66) therapy beam. 6 figs., 11 refs., 4 tabs
