Radiocarbon Mechanism of Aging

Rejuvenation Research, 2006
A hypothetical mechanism of 14 C-generated influence on a person's rate of aging is offered. The mathematical description and the following approbation of the radiocarbon mechanism of aging made it possible to coordinate the Gompertz and Strehler-Mildvan laws and ...

Radiocarbon-calendar age relationship

Earth and Planetary Science Letters, 1971
Abstract Radiocarbon dated tree-rings from eight laboratories were analyzed by multiple regression and 250 yr means to determine the relationship between radiocarbon dates reduced to a common base and tree-ring (calendar) dates for the last 7100 yr.

Radiocarbon Age of a Nevada Mummy

Science, 1965
Skin tissue, bone collagen, and vegetal clothing from a well-preserved Indian mummy from a dry cave in Nevada have been analyzed radiochemically. The age is about 2500 years; the ages obtained for the various samples were in close agreement.

Radiocarbon Age-Determinations From Lignotubers

Australian Journal of Botany, 1988
Large plate-like lignotubers formed by Eucalyptus botryoides Sm. were examined at a site on the south coast of New South Wales. Circumstantial evidence suggests that they are of great antiquity, yet 14C activity measurements of samples taken from lignotubers or associated stump wood corresponded to young ages, and it is clear that low durability of ...

The Radiocarbon Method of Age Determination

American Antiquity, 1956
Five years after the first publication of age measurements by the radiocarbon method (Arnold and Libby 1951) the method has been established as a powerful technique in the study of archaeology. Lists of radiocarbon dates have been published by a number of laboratories (Libby 1951, 1952, 1954, 1955; Kulp 1951, 1952; Broecker and Kulp 1956; Suess 1954 ...
