Abstract
The use of the 93Nb(n,n’) 93mNb reaction to monitor fast neutron fluence is currently being applied at several laboratories around the world. The niobium dosimeter appears to have the desirable properties of providing a neutron fluence measure that corresponds to the changes in the mechanical properties of ferritic materials used in structural components of nuclear reactors and a reaction product with a suitably long half-life [T1/2 = (16.13 ± 0.15)y]. Recently, an effort has been made to develop methods and procedures to routinely analyze niobium dosimeters at the Idaho National Engineering Laboratory (INEL). This effort includes the study of sample preparations, counting techniques, detector calibrations, calibration standards, data analyses and uncertainty evaluations.
