ABSTRACT:
In a method for immobilizing a radioactive noble gas in a zeolite matrix by pressing the noble gas, after heat treatment of the zeolite matrix, into the cavities of the structure of the zeolite matrix under high pressure, and cooling the matrix while maintaining the pressure in order to encapsulate the gas in the cavities, use is made of a zeolite matrix composed of an alkaline earth metal exchanged zeolite having a 0.5 nm pore diameter and of the general composition
