Both 2 3 8 U and 2 3 2 Th decay to stable isotopes of lead. 2 2 2 Rn (t 1 / 2 = 3.8 d) is an intermediate nuclide in the 2 3 8 U series. 2 1 8 Rn (t 1 / 2 = 56 s) is an intermediate nuclide in the 2 3 2 Th decay series. In which series would diffusion of gaseous radon cause the greater error in the computed age of a rock should be identified. Concept introduction: Loss of radon from the sample would increase the U/Pb ratio, so measurement would estimate the age of the rock.

Question

Chapter 14, Problem 14.38PAE

Interpretation Introduction

Interpretation:

Both ²³⁸U and ²³²Th decay to stable isotopes of lead. ²²²Rn (t₁_/₂= 3.8 d) is an intermediate nuclide in the ²³⁸U series. ²¹⁸Rn (t₁_/₂= 56 s) is an intermediate nuclide in the ²³²Th decay series. In which series would diffusion of gaseous radon cause the greater error in the computed age of a rock should be identified.

Concept introduction:

Loss of radon from the sample would increase the U/Pb ratio, so measurement would estimate the age of the rock.
