Although fast neutron activation analysis has
been increasingly used with discrete samples, little
work has been carried out on its possible application
to flowing liquids.
A-relatively small-scale system has been designed
for the neutron irradiation of liquids and its characteristics
studied by the production of isotopes having half-lifes
between 40 and 600 seconds. The limits imposed
by the interfering activity produced by the irradiation
of water have been investigated. The sensitivity of
the system used has been studied for a range of isotopes
and related to the readily available limits of detection
for discrete samples. Calibration curves have been
obtained for a range of elements and the analysis of
mixtures of elements carried out. [Continues.]
