An experimental intercomparison was performed with brick samples from an early medieval building in the west of France, St-Philbert-de-Grandlieu abbey. A potentially complex set microdosimetric problems emerged characterisation measurements, providing a robust test routine procedures used by each laboratory. The dating results obtained using quartz coarse grains and fine grain span over large period time, exhibiting overdispersion, where systematic deviations appear between chronologies. Factors causing such scatter are analysed detail, including internal radioactivity grains, millimetre-scale heterogeneity fabric, observation modelling fading behaviour minerals.
