Table 1.
α- and β-particle emissions by 213Bi and its daughters, emission abundances per decay of 213Bi or daughter nuclide and energies are from the MIRD Radionuclide data and decay schemes book (Eckerman, 2008). Particle ranges (mm) in water were determined from the NIST Star database (electrons) and with the SRIM code (α-particles). Abundance (Ab.) is expressed in % decay and energy (E) in MeV
| α-particles | Ab. (%/decay) | E (MeV) | range (μm) | ||
|---|---|---|---|---|---|
| 213Bi | 1.94 | 5.87 | 46.47 | ||
| 213Po | 100 | 8.38 | 81.75 | ||
| β-particles | Ab. (%/decay) | Emean (MeV) | range (mm) | Emax (MeV) | range (mm) |
| 213Bi | 97.91 | 0.434 | 1.45 | 1.422 | 6.65 |
| 209Tl | 100 | 0.655 | 2.55 | 1.944 | 9.48 |
| 209Pb | 100 | 0.197 | 0.44 | 0.644 | 2.49 |
