Shortest half life isotope
Splet14. dec. 2024 · The half-life is the amount of time it takes for a given isotope to lose half of its radioactivity. If a radioisotope has a half-life of 14 days, half of its atoms will have decayed within 14 days. In 14 more days, half of that remaining half will decay, and so on. Splet27. mar. 2024 · The lower the activation energy, the more likely in any given slice of time it will be that the alpha gets ejected, which yields a short half-life. The higher the activation energy, the less likely, and you have a longer half-life. Share Cite Improve this answer Follow answered Mar 27, 2024 at 3:19 niels nielsen 82.9k 15 118 209 Add a comment
