High-Precision 14 C Measurement of German and Irish Oaks to Show the Natural 14 C Variations from 7890 to 5000 BC
The availability of absolutely (dendrochronologically) dated German oak has allowed the Belfast laboratory to extend its published high-precision 14 C measurements of Irish oak (Pearson et al. 1986) by 2680 yr. The samples were selected at contiguous 20-yr intervals, following a precedent adopted and considered satisfactory in previous publications. All samples were measured for at least 200,000 counts within the 14 C channel. The statistical cou…
High-Precision Bidecadal Calibration of the Radiocarbon Time Scale, 500–2500 BC
The sole purpose of this paper is to present a previously published 14 C data set to which minor corrections have been applied. All basic information previously given is still applicable (Pearson & Stuiver 1986). The corrections are needed because 14 C count-rate influences (radon decay in Seattle, a re-evaluation of the corrections applied for efficiency variation with time previously unrecognized in Belfast) had to be accounted for in more deta…
High-Precision Bidecadal Calibration of the Radiocarbon Time Scale, AD 1950–500 BC and 2500–6000 BC
The radiocarbon ages of dendrochronologically dated wood spanning the AD 1950–6000 BC interval are now available for Seattle (10-yr samples, Stuiver & Becker 1993) and Belfast (20-yr samples, Pearson, Becker & Qua 1993; Pearson & Qua 1993). The results of both laboratories were previously combined to generate a bidecadal calibration curve spanning nearly 4500 years (Stuiver & Pearson 1986; Pearson & Stuiver 1986). We now find that minor correctio…
How to cope with calibration
The first calibration curve, published by Suess in 1967 (Suess 1967), was a wiggly thing arrived at by a process Suess called 'cosmic schwung'. Later curves used more formal statistical methods, including Clark's published in ANTIQUITY (Clark 1975), which came to be one of the most used. It would be good to have the new standard curves available in ANTIQUITY, but they are far too bulky. We recommend the now-indispensable calibration issue of Radi…
High-Precision Calibration of the Radiocarbon Time Scale, AD 1950–500 BC
Radiocarbon ages of dendrochronologically-dated wood spanning the last 4500 years were determined at both the Seattle and Belfast laboratories. The combined results are reported in this issue of radiocarbon in two papers, with this paper covering the AD 1950—500 BC interval, and the twin (Pearson & Stuiver, 1986) covering the 500 BC–2500 BC interval
High-Precision Calibration of the Radiocarbon Time Scale, 500–2500 bc
This paper is a twin paper to that of Stuiver and Pearson (1986) which covers the time period ad 1950–500 bc. The combined radiocarbon ages of dendrochronologically dated wood presented in this paper covers the time period 500–2500 bc
High Precision Radiocarbon Dating by Liquid Scintillation Counting Applied to Radiocarbon Time-Scale Calibration
The precision quoted on a radiocarbon date is often misleading. Improvement in the accuracy of measurement is discussed together with the use of appropriate precisions. The effect of high accuracy in 14 C dating and meaningful precisions are illustrated and applied to radiocarbon time-scale calibration. Intercomparison of such calibrations reveals a significant continuous saw-tooth pattern of short-term periodicity
Precise 14 C Measurement By Liquid Scintillation Counting
Radiocarbon dating involves a comparison of the count rate of sample carbon with that of modern reference standard material. To calculate a date the ratio Z must be determined where
