Abstract
The rate of ejection of alpha-recoil thorium-234 into solution from the surface of zircon sand gives an alpha-recoil range of 550 angstroms. The alpha-recoil thorium-234 atoms ejected into the groundwater may supply excess uranium-234. In pelagic sediments, ejected alpha-recoil thorium-234 may contribute to the supply of mobile uranium-234 in the sedimentary column.
摘要
从锆砂表面排入溶液中的钍-234 的发射率给出了 550 埃的α反冲射程。排入地下水的α反冲钍-234 原子可能提供过剩的铀-234。在远洋沉积物中，发射的α反冲钍-234 可能有助于在沉积柱中提供可移动的铀-234。
