Radiation used carbon 14 dating

Various scanning devices and techniques have been developed, including tomography...

P) have been valuable in identifying the intermediate compounds formed during carbon assimilation.

Gamma rays can easily penetrate pipes (even if they are underground) and reach the detector.

Both alpha and beta particles would not pass through pipes, so could not be used.

Carbon-14 is radioactive, with a half-life of about 5,700 years.

For more information on cosmic rays and half-life, as well as the process of radioactive decay, see How Nuclear Radiation Works.

Another isotope, carbon-14, is useful in studying abnormalities of metabolism that underlie diabetes, gout, anemia, and acromegaly.­The carbon-14 atoms that cosmic rays create combine with oxygen to form carbon dioxide, which plants absorb naturally and incorporate into plant fibers by photosynthesis.Animals and people eat plants and take in carbon-14 as well.This allows corrections to be made on radiocarbon dates in order to produce more accurate dates.Radiocarbon dating, or carbon-14 dating, can be used to date material that had its origins in a living thing as long as the material contains carbon.
