Each nonradioactive isotope atom is present in an amount sufficient to increase the total amount of the nonradioactive isotope atom above the total amount found in the manufactured composition, material or device in the absence of adding the nonradioactive isotope atom to increase said total amount. The ratio(s) of the at least two nonradioactive isotopes in the manufactured composition, material or device are measurably different than the ratio(s) found in the manufactured composition, material or device in the absence of adding the nonradioactive isotope atom to increase said total amount.
