Question The U-Pb dating method relies on two separate decay chains, one of which is the uranium series from 238 U to 206Pb with an apparent half-life of 4.47×10⁹ years. V 1st attempt See Periodic Table Write your answer in decimal form using at least three significant figures. A meteorite is thought to be 1.26×10⁹ years old. Calculate the theoretical mass ratio of 206pb to 238U that should be observed when uranium-lead (U-Pb) dating is performed. = 206pb / 238U
