WebThe rate of decay is important (it's very slow so less harmful) but the lack of harm can also be attributed to the type of radiation. If I remember correctly the two main radioactive isotopes found in the human body are carbon-14 and potassium-40. Neither of these produce the alpha particles or gamma rays which are the most harmful internally. WebApr 24, 2024 · Geologists regularly use five parent isotopes as the basis for the radioactive methods to date rocks: uranium-238, uranium-235, potassium-40, rubidium-87, and samarium-147. These parent radioisotopes change into daughter lead-206, lead-207, argon-40, strontium-87, and neodymium-143 isotopes, respectively. shut down apple watch 6
