Validation of radial dose function for ${\hspace{0.17em}}^{125}\mathrm{I}$ model 6702 (a) and ${\hspace{0.17em}}^{192}\mathrm{I}\mathrm{r}$ Flexisource (b). The ${\hspace{0.17em}}^{125}\mathrm{I}$ and ${\hspace{0.17em}}^{192}\mathrm{I}\mathrm{r}$ mcg(r) data are compared with published data by Hedtjarn et al. ⁽¹⁹⁾ and Granero et al., ⁽²⁰⁾ respectively. Maximum differences between the 6702 and Flexisource references with this study are less than 1.4% and 1.8%, respectively. The MC uncertainties are at most 2.5%.
