“…The challenge of finding a single γ-ray window that linearizes the decay can be approached by recording list-mode data and then adjusting that window offline. The linearity method of Grigorescu (1973) was extended to 54 Mn and 65 Zn by Havelka et al (2006).…”

The 4πβ-γ coincidence counting method and its close relatives are widely used for the primary standardization of radioactivity. Both the general formalism and specific implementation of these methods have been well-documented. In particular, previous papers contain the extrapolation equations used for various decay schemes, methods for determining model parameters and, in some cases, tabulated uncertainty budgets. Two things often lacking from experimental reports are both the rationale for estimating uncertainties in a specific way and the details of exactly how a specific component of uncertainty was estimated. Furthermore, correlations among the components of uncertainty are rarely mentioned.To fill in these gaps, the present article shares the best-practices from a few practitioners of this craft. We explain and demonstrate with examples of how these approaches can be used to estimate the uncertainty of the reported massic activity. We describe uncertainties due to measurement variability, extrapolation functions, dead-time and resolving-time effects, gravimetric links, and nuclear and atomic data. Most importantly, a thorough understanding of the measurement system and its response to the decay under study can be used to derive a robust estimate of the measurement uncertainty.

“…In such a scheme, the typical dead-time correction formulae pertaining to the use on non-extendable dead times are not applicable, and approximate correction formulae have been proposed for this hardware scheme [23], particularly as related to the implementation of a variant of the Pulse Mixing Method of radionuclide standardization [24]. This system was recently used in a study examining the optimal gamma-energy window settings to achieve linear efficiency-extrapolations for various electron-capture nuclides [25].…”

The 4πβ-γ coincidence method for the absolute determination of nuclear disintegration rates has for decades been successfully applied to a variety of radionuclides, via the use of suites of dedicated analogue electronic modules. The high cost of procurement and maintenance of such systems, as well as the requirement for highly experienced technicians to perform the data collection have prompted the design of more flexible data collection techniques. Recent advances in digital signal acquisition technology have facilitated the possibility of storing pulse information from multiple detector systems along with a time stamp for each recorded event, allowing various radionuclide standardization techniques (based on the concept of 4πβ-γ coincidence counting) to be implemented 'offline' via the use of dedicated software routines. This brief paper reviews the progress in the development of such 'digital coincidence counting' systems used in the field of radionuclide metrology and may be viewed as a companion article to other papers (in this issue) on primary methods for radionuclide standardization.
