Abstract

Liquid scintillation counting (LSC) techniques can be used for radionuclide standardization when the calculation of detection efficiency is possible. This is done using a model of the physicochemical processes involved in light emission and also of the statistics of photon emission: the free parameter model. This model can then be applied in two ways: by deducing the free parameter from the measurement of a tracer (the CIEMAT/NIST method) or by calculating this free parameter from coincidence ratio in a specific LS counter (the TDCR method). The purpose of this paper is to describe both these models and some practical issues that need to be addressed if LSC is to be effectively used in radionuclide metrology.

使用液体闪烁计数的放射性核素计量

液体闪烁计数(LSC)技术可以用于放射性核素标准化，当检测效率的计算是可能的。这是使用光发射的物理化学过程模型和光子发射的统计模型来完成的:自由参数模型。该模型可以通过两种方式应用:通过从示踪剂的测量推断自由参数(CIEMAT/NIST方法)或通过特定LS计数器的符合比计算该自由参数(TDCR方法)。本文的目的是描述这两个模型和一些需要解决的实际问题，如果LSC有效地用于放射性核素计量。

期刊介绍： Published 6 times per year, Metrologia covers the fundamentals of measurements, particularly those dealing with the seven base units of the International System of Units (metre, kilogram, second, ampere, kelvin, candela, mole) or proposals to replace them. The journal also publishes papers that contribute to the solution of difficult measurement problems and improve the accuracy of derived units and constants that are of fundamental importance to physics. In addition to regular papers, the journal publishes review articles, issues devoted to single topics of timely interest and occasional conference proceedings. Letters to the Editor and Short Communications (generally three pages or less) are also considered.
