WebDec 17, 2024 · By observing how fast U-238 decays into lead-206, we can calculate the half-life of U-238. This is a theoretical calculation, and we can therefore determine that the half-life of U-238 is 4.5. A very common rock that contains U-238 is granite. If we look at some of the very small zircon crystals in granite, we can accurately measure how much …
