Scott Schwahn's reply mentioned the variation of cross sections with energy.
In addition, the average kinetic energy of the recoil proton varies,
high energy neutrons generally produce higher energy recoil protons,
which have a lower LET, and so a smaller QF.
i.e. the neutron QF depends (in part) on the QF of the recoil proton.
