Is carbon 14 natural or synthetic
WebIs carbon-14 natural or synthetic? Carbon 14 is a radioactive isotope of carbon which is naturally occurring in all agricultural products. It is produced by cosmic ray interaction with nitrogen in the atmosphere and is subsequently incorporated in predictable quantities into plants by photosynthesis.
