Cesium chloride, an alkaline mineral salt, is part of a nutrition plan called "high pH therapy" which focuses on using a combined diet and supplement approach to balancing body pH by reducing the load on overworked acid-buffering systems.
The NRC will host a public meeting to solicit public input on major issues associated with the draft policy statement regarding the current use of certain forms of Cs-137 sources used by NRC- and Agreement State-licensees.

Caesium is an alkaline metal (please do not confuse it with the artificially-manufactured and radioactive caesium 137) and caesium chloride is the salt thereof. Cancer cells are known to have a far lower cell membrane potential.
Cesium is produced in high yield fission of uranium and plutonium. Radioactive cesium needles are a radiation hazard for radiotherapists (16). In this age of nuclear reactors, i.e. Chernobyl, radioactive cesium exposure may be a growing problem.
Because of its high solubility in water, caesium chloride is highly mobile and can even diffuse through concrete. This is a drawback for its radioactive form which urges a search for more stable radioisotope materials. Commercial sources of radioactive caesium chloride are
The cesium chloride (CsCl) source of Cs ions and the strontium chloride (SrCl 2) source of Sr ions and metal salts for the source of Fe ions were purchased from Wako Pure Chemicals (Tokyo, Japan).
