Carbon 14 has a half-life of 5,780 years, and is continuously created in Earth's atmosphere through the interaction of nitrogen and gamma rays from outer space.
It will, therefore, have the same proportion of 14 C as the atmosphere, or in the case of marine animals or plants, with the ocean.
A 1 ml sample was extracted and sent to Prof.
It expands on the principles already laid out in the articles on Principles of Radiocarbon Dating and 00040.
The book covers the two major groups of applications: the use of radionuclides as tracers for studying transport and mixing processes: and as time markers to address problems of the dynamics of such systems, manifested commonly as the so-called residence time in these systems.
