Belfast Radiocarbon Dates VI [PDF]
Radiocarbon, 1970 The dating equipment and operating conditions remain essentially as previously described. This list includes some small samples counted at a filling pressure equivalent to 76cm Hg. at 20°C. Carbon isotope ratios were obtained and calculated as described (R., 1973, v. 15, p. 212). All samples are from Ireland.

Between a rock and a soft place: Using optical ages to date ancient clam gardens on the Pacific Northwest. [PDF]
PLoS ONE, 2017 Rock-walled archaeological features are notoriously hard to date, largely because of the absence of suitable organic material for radiocarbon dating. This study demonstrates the efficacy of dating clam garden wall construction using optical dating, and ...

Chronology of Central European Impulses in the Volga Forest Region: Fatyanovo and Abashevo Cultures
Поволжская археология, 2023 There is a difference in chronology based on radiocarbon dating and historical dates associated with Near Eastern written sources. With the introduction of AMS dating, this gap has become smaller, but has not disappeared.

Radiocarbon dating — modern state, problem, prospects of development and use in archaeology
Вестник археологии, антропологии и этнографии, 2016 Basic principles of radiocarbon dating are presented in the article. History of the method development and modern state are shown. Difficulties appeared under the radiocarbon dating and approaches, permitting to present the received results correctly are

The Problems of Radiocarbon Dating [PDF]
Science, 2005 In their Perspective “The boon and Bane of radiocarbon dating” (21 Jan., p. [362][1]), T. P. Guilderson et al. raise some important issues in radiocarbon (14C) dating. They discuss the problems of calibrating 14C dates that fall within “age plateaus” of the 14C calibration curve and ...

, 2020 For decades, researchers have employed sets of radiocarbon dates to reconstruct trends in ancient human populations. The overarching assumption in this analysis is that the frequency of dates is proportional to the magnitude of past human activity. Thus,

Assessment of oxygen plasma ashing as a pre-treatment for radiocarbon dating [PDF]
, 2009 This study investigates the potential of low-temperature oxygen plasma ashing as a technique for decontaminating charcoal and wood samples prior to radiocarbon dating.

Documenta Praehistorica, 2018 The strengths of formal Bayesian chronological modelling are restated, combining as it does knowledge of the archaeology with the radiocarbon dating of carefully chosen samples of known taphonomy in association with diagnostic material culture.

Towards achieving low background levels in routine dating by liquid scintillation spectrometry [PDF]
, 2004 International radiocarbon intercalibration studies have revealed that radiometric laboratories using liquid scintillation (LS) spectrometry of benzene reported, on average, younger ages for near-background standards than either gas proportional counter ...
