Abstract

Significant resources have been invested in Metrology 4.0 with the advent of digital transformation. Cyber-physical systems (CPS) and digital twin (DT) technologies can be implanted in radiation applications, such as a calibration laboratory. Our objective was to create a pilot project of a CPS of a lab, with an air kerma measurement process as the DT, starting from a Monte Carlo simulation. The discrepancy between virtual and physical measurement results was approximately 10⁻⁶, which is expected given the inherent characteristics of Monte Carlo codes applied to ionizing radiation. A workflow was developed to integrate Monte Carlo simulations within the DT framework. A pilot project of an interlaboratory comparison between two DT laboratories was developed based on the results of this paper.
