Query: Neutron hardness of EJ-276 scintillation material   This paper presents the results of the fast neutron irradiation (E$_n$ >
0.5MeV) of an EJ-276 scintillator performed in the MARIA research reactor with
fluence up to 5.3$\times$10$^{15}$ particles/cm$^2$. In our work, four samples
with size $\phi$25.4~mm$\times$5~mm were tested. The changes in the light
yield, emission and absorption spectrum and neutron/gamma discrimination using
PuBe source before and after irradiation are presented. The figure of merit in
neutron/gamma discrimination based on the charge integration method for
different neutron fluences and different short gate integration times are
determined.
