Accurate dose rate determination is crucial for trapped charge dating (TCD) applications, such as using optically stimulated luminescence (OSL), thermoluminescence (TL), and electron spin resonance (ESR). The μDOSE and μDOSE+ systems provide efficient solutions for this task through simultaneous α and β-counting along with 220Rn/216Po, 219Rn/215Po, 212Bi/212Po and 214Bi/214Po decay pair detection.This paper outlines practical guidelines and optimized laboratory procedures that enhance the performance and data reliability of these systems. We detail critical protocols, including sample homogenization methods to minimize α-particle overcounting, standardized calibration routines using International Atomic Energy Agency reference materials to ensure the reliability of instrument output data, and strategies for managing laboratory environmental conditions such as airborne 222Rn interference through automated measurement delays. Furthermore, we address the necessity of isolating the systems from external high activity sources, such as built-in β sources in luminescence readers, for obtaining the lowest systems backgrounds. While these systems are commercially available, this paper represents the comprehensive compilation of operational best practices derived from years of extensive experience since the first introduction of these systems in 2018.We show that adopting these practices reduces measurement uncertainty, optimizes the measurement time, and improves system stability to ensure high-precision dose rate results for TCD chronologies.
