DETERMINATION OF B, SM AND GD IN TWENTY‐THREE GEOLOGICAL REFERENCE MATERIALS BY NEUTRON‐CAPTURE PROMPT GAMMA‐RAY ACTIVATION ANALYSIS (PGAA)

Abstract

Eleven USGS geological reference materials and twelve French geological reference materials have been measured for B, Sm and Gd concentrations by prompt‐gamma activation analysis. For those materials that have already been analysed, our data is in agreement with published recommended values. These values constitute the first measured data for several French geological reference materials
