Change: Ruthenium-106 emits beta particles with a maximum energy of 39 keV, and can be counted by itself only with a detector sensitive to very low-energy beta particles. Its rhodium-106 daughter, however, emits energetic beta particles and gamma rays that can be measured with most beta or gamma detectors. QA View changes from previous version. (Word count: 1524)
