Two scintillators, a Li-6 loaded ZnS(Ag) inorganic
scintillator and a
natural boron loaded (10 % concentration by weight)
plastic
scintillator, were evaluated for dose measurements in
accelerator-
based boron neutron capture therapy (ABNCT) using
various
monoenergetic neutrons generated via the
Li-7(p,n)Be-7 reaction.
Protons to initiate the reaction were obtained from
the Van de
Graaff accelerator at the University of Massachusetts
Lowell.
While the inorganic scintillator has pronounced
response to thermal
neutrons, the boron loaded plastic scintillator is
quite sufficient for
detecting signals due to both fast and thermal
neutrons, as well as
gamma rays. The plastic scintillator can be used in
mixed beam
dosimetry for fast neutrons, thermal neutrons, and
photons using
pulse height analysis. Its fast response is suitable
for making real
time dose measurements as well.
