Towards a radiocarbon calibration for oxygen isotope stage 3 using New Zealand kauri (Agathis australis) [PDF]
, 2007 It is well known that radiocarbon years do not directly equate to calendar time. As a result, considerable effort has been devoted to generating a decadally resolved calibration curve for the Holocene and latter part of the last termination.

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.

DENDROCHRONOLOGY AND RADIOCARBON DATING [PDF]
Radiocarbon, 2021 ABSTRACTBoth dendrochronology and radiocarbon (14C) dating have their roots back in the early to mid-1900s. Although they were independently developed, they began to intertwine in the 1950s when the founder of dendrochronology, A. E. Douglass, provided dated wood samples for Willard Libby to test his emerging 14C methods.

Biases in radiocarbon dating of organic fractions in sediments from meromictic and seasonally hypoxic lakes [PDF]
Bulletin of the Geological Society of Finland, 2019 We present here radiocarbon dating results from two boreal lakes in Finland, which are permanently (meromictic) or seasonally stratified and contain continuous sequences of annually laminated sediments that started to form in the early Holocene.

Local variance of atmospheric 14C concentrations around Fukushima Dai-ichi Nuclear Power Plant from 2010 to 2012 [PDF]
, 2017 Radiocarbon (14C) has been measured in single tree ring samples collected from the southwest of the Fukushima Dai-ichi Nuclear Power Plant. Our data indicate south-westwards dispersion of radiocarbon and the highest 14C activity observed so far in the ...

Social and biophysical vulnerability of prehistoric societies to Rapid Climate Change
Documenta Praehistorica, 2010 Previous studies of the impact of Rapid Climate Change (RCC) on prehistoric com- munities have often been restricted in their explanatory power due to the lack of an appropriate analytical tool capable of combining palaeoclimate data with archaeological ...

Molecules, 2023 The investigation of the impact of the Fukushima accident is still going on although more than ten years have passed since the disaster. The main goal of this paper was to summarize the results of tritium and radiocarbon determinations in different ...

A radiocarbon database for Scottish archaeological samples [PDF]
, 2000 For the majority of dating laboratories and their respective user communities, the journal Radiocarbon is no longer regarded as the medium for primary publication of radiocarbon measurements.

Concepts of probability in radiocarbon analysis
Documenta Praehistorica, 2011 In this paper we explore the meaning of the word probability, not in general terms, but restricted to the field of radiocarbon dating, where it has the meaning of ‘dating probability assigned to calibrated 14C-ages’.
