Abstract: Systems and methods are provided for the removal and disposal of radium form an aqueous medium. The systems and methods include the removal of radium from a source by contact with either natural or synthetic zeolite. The spent zeolite is monitored for radiation levels and replaced with fresh zeolite when the level of radioactivity reaches approximately 9,000 pCi/g. Spent zeolite is disposed of at a low-level radioactive waste site. A system for monitoring and maintaining radium removal and disposal by an off-site provided is also disclosed.
