Vm. Novikov, A METHOD FOR MONITORING OF GD CONCENTRATION IN GD-LOADED SCINTILLATORS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 366(2-3), 1995, pp. 413-414
A method is described for the determination of the Gd content in liqui
d scintillators, based on detection of X-rays emitted after neutron ca
ptures on Gd. A sensitivity of similar to 10 ppm of Gd by weight (for
Gd concentration of similar to 100 ppm) and similar to 50 ppm (for Gd
concentration of similar to 1000 ppm) is achieved in a short measureme
nt time, with modest equipment available in most physics laboratories.
