Isotopic Disequilibrium of Uranium: Alpha-Recoil Damage and Preferential Solution Effects

ROBERT L. FLEISCHER 1

1 General Electric Research and Development Center, Schenectady, New York 12301

Preferential loss of uranium-234 relative to uranium-238 from rocks into solutions has long been attributed to recoiling alpha-emitting nuclei. Direct evidence has been obtained for two mechanisms, first, recoil ejection from grains, and now release by natural etching of alpha-recoil tracks. The observations have implications for radon emanation and for the storage of alpha-emitting radioactive waste.
