AFTER full discussion of the new determinations1–3 of the half-life of carbon-14, the Fifth Radiocarbon Dating Conference, meeting at Cambridge (see p. 943 of this issue of Nature), adopted the following resolution: 
An apparatus for beta-counting used in a radiocarbon dating laboratory
Abstract This paper describes the beta-counting apparatus of the radiocarbon dating laboratory at CRAD Udine Italy. Some possible improvements of the overall performance are discussed.
Modern aspects of radiocarbon datings
The radiocarbon method for radioactive-age determination is discussed and recent developments in the fixing of the half-life time of14C are reviewed. The occurrence and causes of variations inExpand
UCLA Radiocarbon Dates II
The measurements reported in this list have been made in the Isotope Laboratory at the Institute of Geophysics, UCLA during 1962. Dates have been calculated on the C 14 half life of 5568 years andExpand
University of Georgia radiocarbon dates IV.
Carbon-14 dates, bone, shell, wood and charcoal, samples from United States sites; for reference to part I, see this Bibliography Vol. 35, No. 10, 06 E71-30299.
Radiocarbon dating: a scientific overview
The review provides scientific and basics view on radiocarbon dating. However, his presentation, calibration and interpretation of radiocarbon ages are misleading in some cases, and important wideExpand

Evidence is presented to show that the uncertainties due to effusive separation and the dependence of the sensitivity constant on the isotopic abundance of carbon-14 are small, and it is proposed to reduce the value of the half-life of Carbon-14 determined by Mann, Marlow and Hughes to 5745 ± 50 years.

Dating and environment using long-lived radionuclides
SummaryA brief review of the use of long-lived radionuclides to study our environment at large is presented. The main advance in this field is due to the development of accelerator mass spectrometryExpand

Reevaluation of dating results for some 14C - AMS applications on the basis of the new calibration curves available
In this paper we describe briefly some characteristics of the Accelerator Mass Spectrometry (AMS) technique and the need of corrections in the radiocarbon ages by specific calibration curves. Then weExpand
USDA Sedimentation Laboratory radiocarbon dates I.
Carbon-14 dating using the benzene counting method was done on contemporary samples from Texas and Mississippi, on interlaboratory check samples of wood from till in mine in Michigan, driftwood fromExpand


The half-life of carbon-14.
Abstract Specific activity measurements on pure samples of carbon dioxide containing respectively 45 and 2 per cent C14 by atoms, using mass spectrometry and proportional counting, have resulted in aExpand
The half-life of carbon-14.
The half-life of C/sup 14/ was determined with an accuracy believed to be higher than that of previously reported values, and technical difficulties encountered in this work, particularly problems of adsorption and the methods used to overcome them, are discussed in detail. Expand
