Radioactivity in interplanetary dustIcarus - Tập 2 - Trang 54 - 1963
Wasson John T.
Most of the radioactivity in interplanetary dust in the region of the Earth's orbit results from interactions with solar protons. The most abundant nuclides having half-lives longer than a few hours in a dust of chondritic composition are Co56, Fe55, Al26, Mn53, Co55, C14, Na22, and Co57. The measurement of ratios of dust radionuclides can provide a means of measuring various time parameters. Amon...... hiện toàn bộ
