Belfast Radiocarbon Dates VI [PDF]
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]
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
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
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]
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 ...

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.

UCLA Radiocarbon Dates VIII [PDF]
The measurements reported were made during the 2nd half of 1967 in the Isotope Lab. of the Inst. of Geophysics and Planetary Physics as a continuation of the UCLA date lists I through VII. Samples were analyzed as CO2-gas at close to one atm in a 7.5 L proportional counter with 3 energy channels described earlier.

Biases in radiocarbon dating of organic fractions in sediments from meromictic and seasonally hypoxic lakes [PDF]
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.

Łódź Radiocarbon Dates III [PDF]
The results presented in this list were obtained from 1986 to 1989. Equipment, measurement and treatment of samples are as reported previously (Kanwiszer & Trzeciak 1984: 111). Age calculations are based on a contemporary value equal to 95% of the activity of NBS oxalic acid standard and on the conventional half-life for 14C of 5568 ± 30 years ...
