CONTRIBUTION TO THE STUDY OF THE PREPARATION OF CESIUM SOURCES (in French)
The manufacture of strong Cs/sup 137/ sources is an operation which poses many problems. These include the choice of salt with regard to its good specific activity and its stability under radiation, and the preparation of this salt in suitable form, either by fusion or by pelleting An investigation was made of volatilization when fusion is used as a means of preparing sources of the two most interesting salts, cesium chloride and cesium sulfate. Cesium sulfate was found to be more volatile than the chloride. Nevertheless, taking into consideration the volatilization of the two salts and the possibility of obtaining a higher density and thus specific activity by compression of the salts, the advantage of choosing compression as a method of encapsulation of the Cs/sup 137/ salt is discussed The manufacture of strong sources also raises the problem of self-absorption in the source. This factor was determined in the case of sources made up with cesium chloride and sulfate. (auth)
