Half-Lives for Several Radioactive Isotopes
Isotope Half-Life[1] Type of Emission[2] Isotope Half-Life[3] Type of Emission[4]
614C 5730 y (β−) 83210Bi 5.01 d (β−)
713N 9.97 m (β+) 83212Bi 60.55 m (αorβ−)
915F 4.1 × 10−22 s (p) 84210Po 138.4 d (α)
1124Na 15.00 h (β−) 84212Po 3 × 10−7 s (α)
  1. y = years, d = days, h = hours, m = minutes, s = seconds ↵
  2. E.C. = electron capture, S.F. = Spontaneous fission ↵
  3. y = years, d = days, h = hours, m = minutes, s = seconds ↵
  4. E.C. = electron capture, S.F. = Spontaneous fission ↵
