“…In addition to the large range of meteorite compositions, a variety of compositional parameters distinguishes lunar meteorites from terrestrial materials. 11 Nondestructive or non-invasive analytical techniques, such as electron probe microanalysis (EPMA), 12,13 X-ray fluorescence (XRF) analysis, 14 laser-induced breakdown spectroscopy (LIBS), 14 and instrumental neutron activation analysis (INAA), 9,15,16 are increasingly used for analyzing the elemental composition of rare and precious lunar materials. INAA is a sensitive radioanalytical method based on measuring characteristic radiation from radionuclides formed by irradiating samples with neutrons.…”

The Moon is a key target for long-term human exploration beyond the Earth. In addition to precious lunar returned samples, lunar meteorites can provide important supplementary information on the composition and evolutionary history of the Moon. Herein, we report the elemental compositions of two lunar meteorites, Northwest Africa (NWA) 4734 and NWA 11111, analyzed using instrumental neutron activation analysis (INAA). Reference materials, including SRM2703 and GWB07105, were used for quality control. The INAA results for most elements in NWA 4734 and NWA 11111 are consistent with the previously reported data obtained by inductively coupled plasma-mass spectrometry analysis within analytical uncertainties. Since the INAA analysis is non-destructive, it can be widely applied to trace element measurements for extraterrestrial samples.
