A material found within the body of an organism trapped in an ice berg had a `""_(6)C^(14)` activity of about 0.144 Bg per g. `""_(6)C^(14)` activity of the living organism is 0.28 Bq per g and its half life 5730 years. The age of organism would be

An archeological sample of wood has half C^(14) activity as compared to that found in fresh wood of the same plant. The half life of C^(14) is 5770 years. The age of archiological sample of wood will be

A piece of wood from the ruins of an ancient building was found to have a "^14C activity of 12 disintegrations per minute per gram of its carbon content. The "^14C activity of the living wood is 16 distintegrations per minute per gram. How long ago did the tree, from which the wooden sample came, die? Given half-life of "^14C is 5760 years.

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

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 decays per minute for every gram of carbon. This activity arises from the small proportion of radioactive ""_(6)^(14)C present with the stable carbon isotope ""_(6)^(12)C . When the organism is dead, its interaction with the atmosphere (which maintains the above equilibrium activity) ceases and its activity begins to drop. From the known half-life (5730 years) of ""_(6)^(14)C , and the measured activity, the age of the specimen can be approximately estimated. This is the principle of ""_(6)^(14)C dating used in archaeology. Suppose a specimen from Mohenjodaro gives an activity of 9 decays per minute per gram of carbon. Estimate the approximate age of the Indus-Valley civilisation.
