Discovered in 1940 by Martin Kamen and Sam Ruben, it is formed by cosmic ray bombardment of nitrogen in the atmosphere. Although a comparatively sparse isotope with a half-life of approximately 5700 years, its distribution in the atmosphere and presence in organic material allows for its use in testing. For 10 points, name this isotope used in radiometric dating to determine the age of an organic sample.
