How is radioactive dating used to determine the age of an object?
a. Both the amounts of radioactive and decay material are measured. Using these with the radioactive material's half-life, the age can be estimated.
b. The amount of radioactive material is measured. Using this with the radioactive material's half-life, the age can be estimated.
c. The amount of decay material is measured. Using this with the radioactive material's half-life, the age can be estimated.
