Dear members,
in analyzing a supposed ancient gold jewelry item by means of PIXE, we have
detected about 1% mass Cd everywhere, and in particular on places far from
being solder joints (else the gold contains about 4% Cu and 2% Ag, on also a
very homgeneous manner).
Any comment would be appreciated, thanks
