A new method for fast neutron dosimetry with a circulating liquid

PDF Version Also Available for Download.

Description

A new approach to fast-neutron dosimetry is described. It involves circulating a liquid with dissolved chemicals between a localized neutron field and a remote area where neutron-induced radioactivities are measured continuously. This approach employs reactions which generate relatively short-lived radioactive byproducts. Sensitivity to the neutron energy spectrum is achieved by choosing several reactions with differing thresholds. Neutron field strengths and their time variations can be derived from experimental data using the known radioactive-decay properties, cross sections, detector efficiencies, liquid flow rates and composition of the liquid. The concept has been demonstrated by measurements which utilized an aqueous solution of yttrium ... continued below

Neutron field strengths and their time variations can be derived from experimental data using the known radioactive-decay properties, cross sections, detector efficiencies, liquid flow rates and composition of the liquid. The concept has been demonstrated by measurements which utilized an aqueous solution of yttrium chloride hexahydrate, a 14-MeV neutron generator and Ge gamma-ray detectors. The {sup 16}O(n,p){sup 16}N, {sup 37}Cl(n,p){sup 37}S and {sup 89}Y(n,n{prime}){sup 89m}Y activation reactions served as dosimeters.
