Because it is a gas, radon exists in the atmosphere. Climate scientists have since the midth century gathered detailed observations of They release radiation until they eventually become stable isotopes of lead. However, one of the most widely used and accepted method is radioactive dating.
It is rarely found in sedimentary or metamorphic rocks, and is not found in all igneous rocks.

Because plants use carbon dioxide for photosynthesis, this isotope ends up inside the plant, and because animals eat plants, they get some as well. Comparison of the amount of argon produced in a nuclear reactor to the amount of argon gives a measure of the age of the rocks. Earth's Spheres and Internal
