Half life of `.^(14)C` is

In a sample of wood, the reading of a counter is 32 dpm and in a fresh sample of tree it is 122dpm . Due to error counter gives the reading 2 dpm in absence of .^(14)C . Half life of .^(14)C is 5770 years . The approximate age (in years) of wood sample is :

The half life of _6C^(14) is 5,700 years .what does it mean?

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

The half-life of C^(14) is 5760 years . For a 200 mg sample of C^(14) , the time taken to change to 25 mg is -

The half-life of ._(6)^(14)C is 5730 year. What fraction of its original C^(14) would left after 22920 year of storage?
