Abstract

A peak 7 cm in extent at the 80% isodose level was obtained in the depth damage profile of chromosome aberrations in lymphocytes from blood samples exposed to pimesons. The peak to plateau ratio was 1.4 for dicentrics and 1.6 for total aberrations. This was achieved by superimposing beams of 128, 146 and 166 MeV/c as suggested by a simple model and previously published results. It was observed that the effect of the highest momentum pions was over-estimated, resulting in an early gradual fall off with depth and a useful peak 2 cm less than predicted.
