Carbon-14, an unstable isotope of carbon, follows a well-knownsequence of decay processes.The decay constants of these processeshave been well established, allowing researchers to determine theage of an artifact knowing both the original amount of and the currentamount.Ionization Inverse Square Law Interaction of RT/Matter Attenuation Coefficient Half-Value Layer Sources of Attenuation -Compton Scattering Geometric Unsharpness Filters in Radiography Scatter/Radiation Control Radiation Safety Radio-carbon dating is a method of obtaining age estimates on organic materials.
To find the age of the artifact, they will need to use the following... The anthropologists who found this artifact would like to know its age.
Carbon-14 is produced in the atmosphere when neutrons from cosmic radiation react with nitrogen atoms: C ratio of 0.795 times that found in plants living today. Solution The half-life of carbon-14 is known to be 5720 years. Radioactive decay is a first order rate process, which means the reaction proceeds according to the following equation: is the quantity of radioactive material at time zero, X is the amount remaining after time t, and k is the first order rate constant, which is a characteristic of the isotope undergoing decay.
Carbon-14 () dating is amethod for finding the age of an organic artifact from the quantityof it contains.
It uses the naturally occurring radioisotope carbon-14 (14C) to estimate the age of carbon-bearing materials up to about 58,000 to 62,000 years old.
Carbon has two stable, nonradioactive isotopes: carbon-12 (12C) and carbon-13 (13C).
