Comparative Study of Pga And INAA for Analyses Of Meteorite Samples
Prompt gamma-ray analysis (PGA) and instrumental neutron activation analysis (INAA) are essential for the study of rare samples such as meteorites because of non-destructivity and relatively being free from contaminations.

| description | Prompt gamma-ray analysis (PGA) and instrumental neutron activation analysis (INAA) are essential
for the study of rare samples such as meteorites because of non-destructivity and relatively being free
from contaminations. The objective of this research is to utilize PGA and INAA techniques for
comparative study and apply them to meteorite analyses. In this study, 11 meteorite samples received
from the Meteorite Working Group of NASA were analyzed. The Allende meteorite powder was
included as quality control material. Results from PGA and INAA for Allende showed in good
agreement with literature values, signifying the reliabilities of these two methods. Elements Al, Ca, Mg,
Mn, Na and Ti were determined by both methods and their results are compared. Comparison of PGA
and INAA data using linear regression analysis showed correlations coefficients r2 > 0.90 for Al, Ca,
Mn and Ti, 0.85 for Mg, and 0.38 for Na. The PGA results for Na using 472 keV were less accurate due
to the interference from the broad B peak. Therefore, Na results from INAA method are preferred. For
other elements (Al, Ca, Mg, Mn and Ti), PGA and INAA results can be used as cross-reference for
consistency. The PGA and INAA techniques have been applied to meteorite samples and results are
comparable to literature values compiled from previously analyzed meteorites. In summary, both PGA
and INAA methods give reasonably good agreement and are indispensable in the study of meteorites. |
