The normal activity of a living matter containing carbon is found to be 15 decays per minute per gram of carbon. An archaeological specimen gives 6 decays per minute per gram of carbon. If the half -life of carbon is 5730 years, estimate the approximate age of the specimen.

The activity of carbon -14 in a sample of charcoal from an archaeological site is 0.04 Bq. Determine the age of the sample. The half life of carbon -14 is 5730 years.

The normal activity of living carbon -containing matter is found to be about 15 decay per minute for every gram of carbon. This activity arises form the small proportion of radioactive ._6C^(14) present with the ordinary ._6C^(12) isotope. When the organism is dead, its interaction with the atmosphare which maintains the above equilibrium activity, ceases and its activity begins to drop. form the known half life (=5730years) of ._6C^(14) , and the measured activity, the age of the specimen can be approximately estimated. This is the principle of ._6C^(14) dating used in archaeology. Suppose a spacimen form Mohenjodaro gives an activity of 9 decays per minute per gram of carbon. Estimate the approximate age of the Indus Vally Civilization.

The activity of carbon-14 in a piece of ancient wood is only 12.5 % . If the half life period of carbon-14 is 5760 years, the age of the piece of wood will be

A bone containing 200 g carbon-14 has beta -decay rate of 375 decay/min. Calculate the time that has elapsed since the death of the living one. Given the rate of decay for the living organism is equal to 15 decay per min per gram of carbon and half-life of carbon-14 is 5730 years.
