WebMay 16, 2024 · When the organism dies, its carbon-14 concentration decreases due to radioactive decay. The half-life of carbon-14 is 5700 years. So after 5700 years, the amount of carbon-14 decreases to half its value. After another 5700 years, it decreases to a quarter of its value. So we can infer that the organism is basically 11400 years old.
