Secondary neutrons in 12 C therapy<br />

MCHIT: 330A MeV 12 C in water<br />

100 events, only neutrons are shown<br />

Comparison with GSI data<br />

(D. Schardt et al.)<br />

The <strong>to</strong>tal dose <strong>from</strong> neutrons is predicted at 1% of the treatment dose for<br />

typical irradiation conditions. This was confirmed by GSI measurements,<br />
