The isotope would not be useful for dating bones that are over a million years old because carbon-14 decay at a constant rate‚ with a half-life of 5730 years. Therefore‚ after 40‚ 000 years‚ les than 1% of the carbon-14 is left in the tissue. As a result‚ there is not enough of the isotope in the tissues to determine the age of the bones. 3. The four
