Abstract
A process for the decontamination of radioactive materials which process comprises the steps of: i) contacting the material to be decontaminated with a dilute carbonate containing solution in the presence of ion exchange particles which either contains or have a chelating function bond to them; and ii) separating the ion exchange particles from the dilute carbonate containing solution. The radioactive materials which are treated may be natural materials, such as soil, or man-made materials such as concrete or steel, which have been subjected to contamination.

A process for the decontamination of radioactive materials which process comprises the steps of:
- i) contacting the material to be decontaminated with a dilute carbonate-containing solution in the presence of ion exchange particles which either contain or have a chelating function bound to them;
- and
- ii) separating the ion exchange particles from the dilute carbonate-containing solution.
A process for decontaminating radioactive materials which comprises the steps of:
- i) providing a porous bag containing ion exchange particles which contain or have a chelating function bound thereto,
- ii) contacting the radioactive materials to be decontaminated with a dilute carbonate-containing solution and in the presence of said porous bag containing said ion exchange particles, and
- iii) separating said porous bag containing said ion exchange particles from said dilute carbonate-containing solution.
A process for decontaminating radioactive materials which comprises the steps of:
- i) contacting the radioactive materials to be decontaminated with a dilute carbonate-containing solution in the presence of ion exchange particles which contain or have a chelating function bound thereto to form a mixture, and
- ii) passing said mixture through pinch-press or belt-press filters to separate decontaminated material from said dilute carbonate-containing solution.
