It is shown that it is possible to use the anal. sensitivity of this method for detn. of the percentage of metallic impurity present in trace quantities, and hence to det. the historical archaeological period to which the bronze belongs. The samples were subjected to a thermal neutron flux of 4.5 X 10¹³ n/cm²/sec for up to 14 hr and the resultant Ãœ3-radiation analyzed by a 512-channel instrument. The peaks show the presence of the following radionuclides: ⁵⁹Fe, ⁶⁴Cu, ¹¹³Sn, ¹¹⁴In, ¹¹⁰Ag, ¹²⁴ Sb, ⁶⁰Co, and ⁶⁵Zn. The content of Sn, In, Ag, and Sb is estd. for 4 samples. Applied to Etruscan bronzes this method shows them to be of low Sn content but with very little impurity. Pb could not be detected. The compn. suggests that the metals used -- AATA
