Dependence of RBE on the type of cell irradiated
•
Cells which exhibit
large shoulders
in
their X-ray survival curves tend to have
high RBEs
•
Cells with
little, if any, shoulder
tend to have
low RBEs
•
There are exceptions, due to the different
interaction mechanisms between low and high LET radiations
e.g.
cell-cycle effect
