INTERCOMPARATIVE STUDIES OF BRACHYTHERAPY TECHNIQUES COMBINED WITH CF-252 BORON NEUTRON-CAPTURE THERAPY

In this work the depth dose distribution for gamma-rays, slow and fast neutrons, nuclear recoils and alpha-particles inside a tumor phantom filled with 100 ppm B-10 in distilled water was measured. The depth do se distributions were measured and represented on three-dimensional pl ots when a Cf-252 neutron source was situated in interstitial, surface and intracavitary brachytherapy techniques. Comparison of the three b rachytherapy techniques when combined with BNCT revealed that the dama ge induced in the tumor by the alpha-particles as nuclear recoils in t he interstitial geometry is much more than the other two techniques.
