It is a foundation for formal quality control at an individual laboratory level, fosters a harmonization amongst laboratories and provides an independent and verifiable measure of interlaboratory comparability for the user. The ATOMKI GPC laboratory took part in the last three International Radiocarbon Intercomparison (TIRI, FIRI, VIRI). The samples' activities spanned the activity range from "modern" to "close to background", and they represented a wide scale of materials. Altogether 29 samples were analyzed during the courses. Six of them were "modern", three were "close to background" and the age of 20 samples varied from 1600 BP to 19 000 B P. In this time span 14 of our measured data agreed with the consensus values at 1s, 5 of them at 2s confidence level. The difference between the consensus and measured values was a bit larger than 2s for TIRI L (whalebone). This sample belonged to the special samples. It was sent to check the minimum carbon quantity for measurements and it contained cc 0.5 g C. The "close to background" means for us 35-40 000 B P. © by the author(s). LA - Hungarian DB - MTMT ER -
