DOI: 10.1016/j.marchem.2017.06.011
Abstract: Abstract Radium (Ra) isotopes are enriched in hydrothermal fluids, have a wide range of half-lives and are minimally impacted by scavenging removal processes; therefore, they have the ability to provide key information on the fate… read more here.

DOI: 10.3390/ma16051935
Abstract: Radium isotopes have traditionally been used as tracers of surface and underground fresh waters in land–ocean interactions. The concentration of these isotopes is most effective on sorbents containing mixed oxides of manganese. During the 116… read more here.
