Nuclear Activation Services Limited (lake sediments) Au

Nuclear Activation Services Limited, lake sediments; Gold by pre-concentration, neutron activation / gamma ray spectroscopy

General Methodology:

Gold was determined on a 5 to 10 gram lake sediment sample, depending on amount of sample available. The sample was fused to produce a lead button, collecting any gold in the sample, which was cupelled in a muffle furnace to produce a silver bead.  The silver beads were irradiated in a neutron flux for 1 hour, cooled for 4 hours, and counted by gamma ray spectroscopy. Calibration was carried out using standard and blank beads.
