Notes:
D
=
P
−
E
1. This is
independent of
α/β
for either late injury
or tumor response.
i.e.
L
and
T
can take
any
values and still
D
=
P
–
E
.
2. Because of
α/β
independence, it follows that
acute
injury will also be identical to the
original plan. In fact,
all
biological effects will
be the same
as the original plan, so long as
their radiation response is described by LQ.
