Radiocarbon, or Carbon, dating is probably one of the most widely used and best known absolute dating methods. Carbon is produced in the upper atmosphere when cosmic rays bombard that the longer the time since death the lower the levels of c14 in organic tissue. The diminishing levels via decay means that the effective limit for using c14 to.

Since carbon is fundamental to life, occurring along with hydrogen in all organic compounds, the detection of such an isotope might form the basis for a method to establish the age of ancient materials.
