“…For analysis of beta-emitters found in the environment (e.g. 3 H, 14 C, 81 Kr, 85 Kr, 90 Sr, 133 Xe, 135 Xe, 241 Pu, and others), gas counting [ 61 – 77 ] and liquid scintillation spectrometers have been used [ 37 , 78 – 80 ]. In some applications, however, radiometric techniques of analysis of long-lived beta-emitters did not allow to carry out state of the art nuclear and environmental research either because of lack of sensitivity or requirement of large samples for analysis.…”

Recent developments in radiometric and mass spectrometry technologies have been associated in the radiometric sector mainly with underground operations of large volume Ge detectors, while the mass-spectrometry sector, represented mainly by accelerator mass spectrometry and inductively coupled plasma mass spectrometry has become the most sensitive technique for ultra-low-level analyses of long-lived radionuclides. These new developments have had great impact on investigations of rare nuclear processes and applications of radionuclides in environmental, life and space sciences. New scientific investigations have been carried out therefore which have not been possible before either because of lack of sensitivity or required large sample size.

Liquid scintillation counting (LSC) is one of the most widely used methods for determining the activity of 241 Pu. One of the main challenges of this counting method is the efficiency calibration of the system for the low beta energies of 241 Pu (E max = 20.8 keV). In this paper we compare the two most frequently used methods, the CIEMAT/NIST efficiency tracing (CNET) method and the experimental quench correction curve method. Both methods proved to be reliable, and agree within their uncertainties, for the expected quenching conditions of the sources.
