It is not possible to predict when an individual nucleus in a radioactive material will decay. Ninety-five percent of the activity of Oxalic Acid from the year 1950 is equal to the measured activity of the absolute radiocarbon standard which is 1890 wood. This is the International Radiocarbon Dating Standard.But it is possible to measure the time taken for half of the nuclei in a radioactive material to decay.This is called the half life of radioactive material or radioisotope.
