DETERMINATION OF 151Sm IN SOIL SAMPLES BY USING LIQUID SCINTILLATION COUNTING METHOD
Известия Томского политехнического университета: Инжиниринг георесурсов, 2022 The relevance. One of the relatively long-lived nuclear fission products is 151Sm (T1/2~90 years). The total cumulative yield of 151Sm upon fission of the isotopes 235U, 239Pu and 238U is 0,46, 1,29 and 0,83 %, respectively. The estimated amount of 151Sm

Low-Afterglow, High-Refractive-Index Liquid Scintillators for Fast-Neutron Spectrometry and Imaging Applications [PDF]
IEEE Trans.Nucl.Sci.56:989-993,2009, 2009 For ion and neutron spectrometry and imaging applications at a high intensity pulsed laser facility, fast liquid scintillators with very low afterglow are required. Furthermore, neutron imaging with fiber (or liquid-core) capillary arrays calls for scintillation materials with high refractive index. To this end, we have examined various combinations of

Pulse-Shape discrimination with the Counting Test Facility [PDF]
Nucl.Instrum.Meth.A584:98-113,2008, 2007 Pulse shape discrimination (PSD) is one of the most distinctive features of liquid scintillators. Since the introduction of the scintillation techniques in the field of particle detection, many studies have been carried out to characterize intrinsic properties of the most common liquid scintillator mixtures in this respect.

Study of infrared scintillations in gaseous and liquid argon - Part I: methodology and time measurements [PDF]
JINST 7:P06015,2012, 2012 A methodology to measure Near Infrared (NIR) scintillations in gaseous and liquid Ar, using Geiger-mode APDs (GAPDs) sensitive in the NIR and pulsed X-ray irradiation, is described. This study has been triggered by the development of Cryogenic Avalanche Detectors (CRADs) with optical readout in the NIR using combined THGEM/GAPD multiplier, which may ...

A comparative study on the influence of the type of acid used for 55Fe and 63Ni determination in steel samples through Liquid Scintillation Counting [PDF]
EPJ Web of Conferences, 2023 In decommissioning of nuclear facilities the presence of activated steel requires the determination, along with other radionuclides, of 55Fe and 63Ni. These can be considered as hard-to-measure-radionuclides because of their low energy beta particles or ...
