S. Pszona, A NEW APPLICATION OF HE-3 AND (BF3)-B-10 PROPORTIONAL-COUNTERS IN A POLYTHENE MODERATOR, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 402(1), 1998, pp. 139-142
A detailed examination of the pulse-height spectra from He-3 and (BF3)
-B-10 proportional counters, placed inside a polythene moderator, and
irradiated by neutrons, has led to the discovery of a ''neutron event
free-energy window''. It has been shown that this window can be used f
or the registration of gamma radiation without disturbing the registra
tion of neutrons. A new method for measuring the ambient dose equivale
nt in mixed neutron-gamma radiation fields has been proposed.
