Abstract  

Recovery of226Ra in analysis is determined using225Ra separated by anion exchange from229Th and233U. Radium is coprecipitated with barium, and purified by ion exchange.226Ra and217At (decay product of225Ra) are measured by α-spectrometry.228Ra is determined both by β-counting228Ac and225Ac separated from228Ra and225Ra, and by α-counting its daughters after the decay of225Ra. Sources for α-spectrometry are prepared by electrodeposition (molecular plating).
