1. Nuclear reactions such as radioactive decay constantly occur in small amounts in the human body and involve isotopes like carbon-14 and potassium-40. 2. These isotopes behave chemically identical to stable isotopes but decay over time, which can damage chemicals that rely on them. However, the damage is typically rare enough that the body can repair it. 3. Carbon-14 decay is the basis for carbon dating, which can determine the age of once-living materials up to 60,000 years old by measuring their rema
