Analytical Package Description

Laboratory: Becquerel Laboratories Inc., Mississauga, Ontario

Name: Becquerel (NGR) INAA Au reproducibility test (more)

To provide additional information on gold data, samples with INAA gold concentrations greater than or equal to 8 ppb were rerun by splitting the irradiated material into two portions, each of which was re-irradiated and counted.  Two additional analyses returning similar values suggest a finely divided and/or organically bound source for the gold.  Two splits with distinctly different values probably contain larger gold grains unequally distributed throughout the original sample (the “nugget” effect).
