A simplified method for preparation of 137Cs pollucite γ

Pollucite is a chemical form of caesium compound exist ing as ore. The compound pollucite has suitable properties such as high melting point (about 1700) and insolubility to water. In 1967, OLOMBEL et al., CEA, proposed the pol- Prepaatton lucite core for a 1Cs y-ray source and developed a process method of synthesizing the pollucite core.(')

Caesium Academic Dictionaries and Encyclopedias

The mining of pollucite ore is a selective process and is conducted on a small scale in comparison with most metal mining operations. The ore is crushed, hand-sorted, but not usually concentrated, and then ground. Caesium is then extracted from pollucite mainly by three methods acid digestion, alkaline decomposition, and direct reduction.
