There is a need to find a replacement for the 252 Cf sources currently used in Standards-
based performance testing of neutron instrumentation. This is a result of its relatively short …

One of the most common radionuclide neutron sources used for the calibration of detectors
is 252Cf. However, these sources also contain 250Cf, which is present in the material from …

One of the most common radionuclide neutron sources used for calibration of detectors is
252Cf. However, these sources are not isotopically pure and also contain the neutron …

A new, stronger 252Cf source (serial number SR-CF-3050-OR) was obtained from Oak
Ridge National Laboratory (ORNL) in 2014 to supplement the existing 252Cf sources which …

Californium-252 is used as a neutron calibration source for passive neutron correlation
counting. Source age and isotopic information are needed to make decay corrections to the …

A Cf-252 neutron source is widely used for testing and calibrating neutron multiplicity
counters. General equations for calculating the time-dependent strength and multiplicity of …

A new standard neutron source based on curium-248 has been developed, prepared, and
certified. The curium-248 isotope is more long-lived than californium-252. The active core of …

This paper presents the characterization of a neutron calibration field of a 241 Am− Be
source using Bonner sphere spectrometer. The characterization of the neutron field in terms …

Californium-252 makes an intense neutron point source that emits 2.34× 1012 n/(sec g)
through spontaneous fission. Sources are being prepared to investigate the value of this …

A multipurpose 14-MeV neutron source based on the T (d, n) 4 He reaction is under
construction in Bratislava. Its basic purpose is to produce intense and pulsed beams of 14 …
