Chapter 10: Problem 77
A nuclear physicist finds \(1.0 \mu g\) of \(^{236} \mathrm{U}\) in a piece of uranium ore \(\left(T_{1 / 2}=2.348 \times 10^{7} \mathrm{y}\right) .\) (a) Use the decay law to determine how much \(^{236} \mathrm{U}\) would had to have been on Earth when it formed \(4.543 \times 10^{9} \mathrm{y}\) ago for \(1.0 \mu g\) to be left today. (b) What is unreasonable about this result? (c) How is this unreasonable result resolved?
