²¹⁹At decay; t_1/2 = 56 s (t = 81 s).

1. ²¹⁹At [a (no g)] ²¹⁵Bi   (97%)
2. ²¹⁹At [b (no g)] ²¹⁹Rn   (3%;   t_1/2 ~ 190 s)

Notes:

1. c.e.: conversion electrons
2. Energies in keV
3. Intensities per `parent' decay of natural U (i.e. 0.956 ²³⁸U, 0.044 ²³⁵U)
4. Data from compilations and amendments in Nuclear Data Sheets to Vol. 64 (1991)
5. g and conversion electron intensities are totals from given level; part may be associated with different (lower energy) primaries
