Libby estimated that the radioactivity of exchangeable carbon-14 would be about 14 disintegrations per minute (dpm) per gram of pure carbon, and this is still used as the activity of the modern radiocarbon standard.Through photosynthesis, plants absorb both forms from carbon dioxide in the atmosphere.
