Which one of the following is the most useful tracer for dating ancient organic artifacts?
Correct answer: B. Carbon-14
- A. Strontium-90
- B. Carbon-14
- C. Iodine-131
- D. Cobalt-60
Explanation
Carbon-14 is a naturally occurring isotope used for radiocarbon dating of organic materials up to about 50,000 years old. Living organisms incorporate C-14, and the decay of this isotope after death allows scientists to determine the age of the remains.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
