WebAug 23, 2024 · Radiometric Dating. Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample. It is founded on unprovable assumptions such as 1) there has been no contamination and 2) the decay rate has remained constant. WebThe precision of a dating method depends in part on the half-life of the radioactive isotope involved. For instance, carbon-14 has a half-life of 5,730 years. After an organism has been dead for 60,000 years, so little carbon-14 is left that accurate dating can not be established. imagewear by walman opticalWebNoun: 1. radioactive dating - measurement of the amount of radioactive material (usually carbon 14) that an object contains; can be used to estimate the age of the object imagewear brands
