$_{88}\text{R}_{\text{a}}^{226}$ is converted into $_{82}\text{P}_{\text{b}}^{206}$ by emission of alpha ( $\alpha$ ) and beta ( $\beta$ ) particles. The number of alpha and beta particles emitted are respectively}

If \( R_1 \) and \( R_2 \) are the radii of the atomic nuclei of mass numbers $27$ and $125$ respectively, then the ratio \( R_2 : R_1 \) is
