1. A system for the neutron activation analysis of fluid media which comprises:

  • a. A first activation analysis loop including a neutron source for generating a neutron flux that includes a substantial flux of thermal neutrons, a radiation detector for sensing gamma radiation produced as a result of activation by said neutron flux, and conduit means for circulating a first portion of fluid proximate to said neutron source and gamma detector;

    b. A second activation analysis loop including a neutron source for generating a fast neutron flux that is substantially free of thermal neutrons, a radiation detector for sensing gamma radiation produced as a result of activation by said fast neutron flux, and conduit means for circulating a second portion of said fluid proximate to said neutron source and gamma detector; and

    c. Pulse spectroscopy means for processing the outputs of said radiation detectors to determine the constituents of said fluid.
