DETERMINATION OF LEAD IN METEORITES BY ALPHA ACTIVATION ANALYSIS
Technical Report
·
OSTI ID:4767052
An alpha activation method has been devised whereby the abundances of Pb/ sup 204/, Pb/sup 206/ and Pb/sup 208/ can be determined on one gram samples with a sensitivity of about 5 x 10/sup -9/ gm/ gm for Pb/sup 206/ and Pb/sup 208/ and 1 x 10/sup -9/ gm/gm for Pb/sup 204/. Re sults on three meteorite samples, Canyon Diablo troilite, the carbonaceous chondrite Murray, and the enstatite achondrite Norton County, indicate the presence of radiogenic lead apparently unsupported by uranium and thorium. One explanation is that these meteorites incorporated this lead when they crystallized. (auth)
