An archeological artifact was subjected to radiocarbon dating. The artifact showed a carbon-14 decay rate of 12.2disintegrations/min per gram of carbon. Carbon-14 has a half-life of 5715 years, and currently living organisms decay at the rate of 15.3 disintegrations/min per gram of carbon. What is the approximate age of the artifact? Select one: A. 371 years old B. 6597 years old C. 851 years old D. 1867 years old

A sample of charred animal bones found in a cave has a carbon-14 decay rate of 5.2 disintegrations per minute per gram of carbon (5.2 dis/min-g C). Living organisms have a decay rate of 15.3 dis/min-g C. The half-life of carbon-14 is 5715 yr. How old is the bone sample?

7.3 The decay rate of the isotope carbon-14 (14C) is often used to establish the date on which carbon-containing matter died. In the upper atmosphere, cosmic radi- ation synthesizes 14C. This process balances the loss of 14C through radioactive decay. Living matter, which exchanges carbon with atmospheric carbon diox- ide and maintains its 14C level, produces 15.3 disintegrations per minute per gram of carbon it contains. Dead organisms no longer exchange carbon with the atmosphere, and the 14C content decreases...

1. The nucleus 14C (half life 5730 y) is used in radiocarbon dating to determine the age of previously living material. (a)A certain sample of wood currently shows a decay rate of 35.0 decays/s of 14C The wood is taken from a structure that was built from a tree that was cut 7,000 years ago. What would have been the 14C decay rate of this wood sample when the tree was cut? (b) Find the total binding energy (in MeV)...
