Distribution of Pa-231 and Ra-226 in rock. An indicator of rock matrix diffusion

Creators

  • 1. Helsinki Univ. (Finland). Dept. of Radiochemistry

Description

Distribution of Ra-226 and Pa-231 in rock has been studied to find signatures that may be attributed to diffusion. The idea of studying these nuclides originated from the need to obtain interpretative support to the findings of U movement in rock. Concentration profiles of Ra-226 and Pa-231 with other U series nuclides were measured across the secondary U accumulations observed in altered rock close to a fracture in the vicinity of U deposit, and in a radioactivity anomaly.
