Problem 40

Natural uranium consists of $${ }^{235} \mathrm{U}$$ (percent abundance = 0.7200 %, $$\lambda=3.12 \times 10^{-17} / \mathrm{s}$$) and $${ }^{238} \mathrm{U}$$  (percent abundance = 99.27 %, $$\lambda=4.92 \times 10^{-18} / \mathrm{s}$$). What were the values for percent abundance of $${ }^{235} \mathrm{U}$$ and $${ }^{238} \mathrm{U}$$ when Earth formed $$4.5 \times 10^{9}$$ years ago?

Text Transcription:

^235 U

lambda=3.12 times 10^17/s

^238 U

lambda=4.92 times 10^18/s
