Dear Dr. Wali,
Radium occurs in nature in one mineral known as radian barite which is among the least soluble minerals precipitated in hot brines and in lignitic coal, simply by its position within the periodical system of elements as a member of the earth alkaline elements. Adding sulfate to the underground water will in a very cost-efficient way lead to a radian-sulfate precipitate.

Dear Farouk,
Radium can be eliminated with sulfonic resins, thus also with conventional softening. The efficacy reported for sweetening process treatment with lime for the removal of radium ranges from 80 to 95%.
With my best regards

Dear All
Thank you for your helpful answers and assistance.
Dr. Farouk Wali
The method that will eliminate radium and let it in a sure disposable form is the classical method of the Curie:: add a barium salt and precipite it with sulphate..
RaSO4 is less solujble than BaSO4 You may send it to a radilogical laboratory. They know what to do..
