Aluminum-26 activities in meteoritesAl-26 activities for 686 Antarctic meteorites and 46 non-Antarctic meteorites are reported. The data set includes new results for 253 Antarctic and 5 non-Antarctic meteorites. Most of the Antarctic specimens were collected from the Allan Hills region, but specimens from other regions were measured as well. The non-Antarctic specimens include freshly fallen meteorites, in which short-lived radionuclides (e.g., Na-22, Mn-54, Co-57, etc.) were also measured. The data were analyzed for terrestrial age distributions, identification of samples with unusual activities, pairing of specimens, and comparisons of Antarctic and non-Antarctic activity distributions.
