Physical Review. Suess said he drew the line showing the wiggles by "cosmic schwung ", by which he meant that the variations were caused by extraterrestrial forces. InMartin Kamen and Samuel Ruben of the Radiation Laboratory at Berkeley began experiments to determine if any of the elements common in organic matter had isotopes with half-lives long enough to be of value in biomedical research. After one half-life passes, half of the remaining nuclei will decay in the next half-life. More broadly, the success of radiocarbon dating stimulated interest in analytical and statistical approaches to archaeological data. There are several other possible sources of error that need to be considered. Similarly, the statement about land organisms is only true once fractionation is taken into account.
Over time, carbon decays radioactively and turns into nitrogen.
