We report the first measurement of the radium ion's $7p$ ${}^{2}P_{3/2}^o$ state branching fractions and improved theoretical calculations. With a single laser-cooled radium-226 ion we measure the $P_{3/2}$ branching fractions to the $7s$ ${}^{2}S_{1/2}$ ground state 0.87678(20), the $6d$ ${}^{2}D_{5/2}$ state 0.10759(10), and the $6d$ ${}^{2}D_{3/2}$ state 0.01563(21).
