•
1 MeV neutrons mainly
accelerate protons which
Neutrons w
R
•
Changing the neutron energy, the accelerated products and how they induce
the biological damage change
•
The balance between these two factors (particle spectrum and LET) is the
origin of the effectiveness variation of neutrons (E)
deposits energy close to their
max LET
•
Contribute of heavier nuclei
accelerated by neutrons
increases with energy with a
maximum around 20 MeV
