THe carbon picked up from the soil is not a significant source of C14.

In a study presented at the meeting of the American Chemical Society, researchers revealed how atmospheric atomic bomb testing changed carbon isotope ratios, allowing easy identification of vintages of wines bottled in the years testing went on.

Also, because carbon dioxide is continuously absorbed by plants and becomes part of their tissues, plants should contain traces of carbon-14.

Since animals consume plants, animals should likewise contain traces of carbon-14.To prove the survivability of nuclear war, Libby built a fallout shelter at his house, an event that was widely publicized.The shelter and house burned down several weeks later, however, which caused physicist and nuclear testing critic .He also dated linen wrappings from the but which Libby’s method applied by others shows to be from a period between 12.In nominating Libby for the Nobel Prize, one scientist stated, “Seldom has a single discovery in chemistry had such an impact on the thinking in so many fields of human endeavour.But those two decades of atomic bomb tests increased the C-14 in the atmosphere.
