Abstract
Using reactor instrumental neutron activation analysis (INAA), experiments have shown that the percent lead in typical bullet leads can be measured to a relative standard deviation of around ±1%, even without use of cadmium. Under the conditions used, the forensically important elements Sb, As, Cu and Sn can be measured at the same time. The other important element, Ag, must still be measured satisfactorily in a separate, short irradiation that utilizes the 24.6 s110Ag (or 2.41 m108Ag) activities.
