CORRECTIONS FOR DRILL-BIT CONTAMINATION IN SAMPLING ANCIENT POTTERY FOR NEUTRON ACTIVATION ANALYSIS |
|
| Authors: | M ATTAS J M FOSSEY L YAFFE |
| Abstract: | The routine measurement of tungsten concentrations in pottery sampled with tungsten-carbide drill bits has enabled the measured concentrations of cobalt, tantalum, and lutetium to be corrected for drill-bit contamination. The corrected data, for cobalt at least, are sufficiently accurate that they regain their value as chemical indicators of pottery provenance. |
