  1. TRONDHEIM NATURAL RADIOCARBON MEASUREMENTS II R. NYDAL Radiological Dating Laboratory The Norwegian Institute of Technology, Trondheim, Norway INTRODUCTION This date list covers the period from September 1958 to December 1959 and a few earlier dates omitted from our first list (Nydal, 1959) . As regards the geologic samples, the accordance between the C14 age and the age predicted from.
  2. Radiocarbon dating is a dating technique based on the decay of the naturally occurring radioactive nuclide 14 C, which has a half-life of 5730 years. The 14 C/ 12 C ratio remaining in a sample can therefore be used to calculate its age
  3. Die Radiokarbonmethode, auch Radiokohlenstoffdatierung, 14 C; C14-Datierung oder Radiokarbondatierung bzw. Radiocarbondatierung, ist ein Verfahren zur radiometrischen Datierung kohlenstoffhaltiger, insbesondere organischer Materialien. Der zeitliche Anwendungsbereich liegt zwischen 300 und etwa 60.000 Jahren. Das Verfahren beruht darauf, dass in abgestorbenen Organismen der Anteil an.
  4. The next global radiocarbon inter-comparison is currently being planned, with samples being sourced. We will distribute the samples by the end of 2019, allowing 6 months for return of the results. This exercise is for AMS facilities, but we will endeavour, if possible to acquire radiometric samples
  5. Radiocarbon is the main international journal of record for research articles and date lists relevant to 14 C and other radioisotopes and techniques used in archaeological, geophysical, oceanographic, and related dating. The journal is published six times a year, and we also publish conference proceedings and monographs on topics related to our fields of interest

The department changed its name from the Department of Archaeometry, in 2014 Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon..

Accelerator mass spectrometry (AMS) allows radiocarbon dating to be carried out by direct counting of 14 C atoms, rather than the conventional counting of radioactive disintegrations. The result is that samples up to 1000 times smaller can be handled. The approach was tested in principle by 1977 and for archaeological operation by 1983. More than 2000 samples per year are now being dated. (2019) Radiocarbon calibration around AD 1900 from Scots pine (Pinus sylvestris) tree rings from northern Norway.

Radiocarbon dating is a two-stage process involving isotope measurements and the calibration against similar measurements made on dendrochronologically dated wood. For our time horizon, it normally provides precision ranges of 100 y to 300 y with 95% probability. To build a chronological megalithic sequence as precisely as possible, we adopted a Bayesian modeling approach, which is applied.
