The artifacts and fossils are used to estimate ages by measuring _ content.
Correct answer: C. radioactive
- A. mineral
- B. chemical
- C. radioactive
- D. all of these
Explanation
One of the most widely known radiometric dating techniques, radiocarbon dating measures the decay of the radioactive isotope Carbon-14 (C-14) in any organic material found in archaeological deposits, such as wood, plants, textiles, and human or animal remains to determine its age.Options A,B&D are incorrect

About Radioactive Decay
Radioactive decay is the spontaneous transformation of unstable nuclei, described by decay constant, activity, half life and the exponential decay law. Work includes alpha, beta and gamma emissions, decay equations and remaining nuclei, with half life distinguished from the time required for complete decay.
