  The gamma to neutron ratio is measured via Pulse Shape Discrimination (PSD)
of a Plutonium Beryllium (PuBe) source and of a rudimentary constructed
Polonium Beryllium (PoBe) source using one organic liquid scintillator detector
and digital signal processing. Furthermore, two organic liquid scintillator
detectors and digital signal processing is used to conduct coincidence counting
on the PoBe source. Measured data is compared to literature. The gamma to
neutron source ratio was found to be 3.67 +/- 0.14 and 1.13 +/- 0.05 for the
PuBe and for the PoBe source respectively. Both ratios are above literature
values for the respective neutron sources. Coincidence counting analysis showed
that the PoBe source emitted two or more coincident gamma-rays or neutrons with
a confidence level of 91.77 % using a coincident window of 40ns and a detector
source distance of 1 mm.
