A sample of wooden artifact is found to undergo 9 disintegration per minute per gram of carbon. What is the approximate age of the artifact? The half life of `._(6)^(14)C` is 5730 years and radioactivity of wood recently cut is 15 disintegrations per minute per gram of carbon.

A sample of wooden aircrafts is found to undergo 9 dp m g^(-1) of .^(14)C . What is appoximate age of aircraffts? The half line of ._(6)^(14)C is 5730 year and rate of disintergration of wood recently cut down is 15 dp m g^(-1) do ._(6)^(14)C ?

A piece of ancient wood shows an activity of 3.9 disintergration per sec. per gram of .^(14)C . Calculate the age of the wood. T_(1//2) of .^(14) C=5570 years. Activity of fresh .^(14)C=15.6 disinteration per second per gram.

A piece of wood form the ruins of an nuclei an ancient building was found to have a .^(14)C activity of 12 disintegrations per minute per gram of its carbon content. The .^(14)C activity of the living wood is 16 disintegrations/minute/gram. How long ago did the trees, form which the wooden sample came, die? Given half-life of .^(14)C is 5760yers .

Ra^(226) has half life of 1600 years. The number of disintegration per second per gram is

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.
