* beta-particle yield of 186Re is 92.5%. ^ Calculated with Geant4 Application for Tomographic Emission (GATE); see Supplementary File S2 for details. v The continuous-slowing-down approximation (CSDA) range was calculated using the maximum energies with equation A.18 from Prestwich et al. (1989) [47].
