“…Until recently, the relatively large amount of sample needed (ca lOg) has precluded the application of conventional 14C measurement (by standard gas-proportional and liquid scintillation counting methods) to the dating of documents, as it has never been permissible to remove a sufficient quantity of material for worthwhile analysis. The same difficulty has sometimes arisen with ancient textiles, eg, two tunics from Tarkhan, Egypt (Burleigh, Matthews, and Ambers, 1982;Hall, 1982), with which individual garments have been too important to allow even partial destruction for dating (although without a precise date their archaeologic value may have been correspondingly diminished). With the advent of (in R L Otlet's terminology) "micro-" and "mini-" methods of 14C measurementby means of accelerators (Hedges, 1981;Stuiver, 1978) and small counters (Iiarbottle, Sayre, and Stoenner, 1979;Otlet and Evans, 1982;Sayre et al, 1981), for which a few milligrams or less of sample are needed, the former constraint of minimum sample size has been removed.…”
