| Cs | Cesium |

| CsCl | Cesium chloride |
| cesium 137 | <radiology> Cs-137, energy: 662 keV (near Mo-99), half-life: 30 years (12 Dec 1998) |

| cesium | <element> A radioactive alkaline (basic) metal element that becomes liquid at slightly above room temperature, it reacts violently with both water and oxygen, as well as with other substances. (09 Oct 1997) |
|---|---|
| cesium chloride | <chemical> Salt that yields aqueous solutions of high density. When equilibrium has been established between sedimentation and diffusion during ultracentrifugation, a linear density gradient is established in which macromolecules such as DNA band at a position corresponding to their own buoyant density. (18 Nov 1997) |
| cesium chloride gradient centrifugation | A type of density gradient centrifugation, a lab technique used to separate or purify nucleic acids. It involves putting cesium chloride and the nucleic acids into a centrifuge to be spun for hours or days. The cesium chloride forms a density gradient (highly dense at the bottom, thinnest at the top), and the different nucleic acids separate along the gradient according to their buoyancies in different densities. (09 Oct 1997) |
| cesium isotopes | Stable cesium atoms that have the same atomic number as the element cesium, but differ in atomic weight. Cs-133 is a naturally occurring isotope. (12 Dec 1998) |
| cesium radioisotopes | Unstable isotopes of cesium that decay or disintegrate emitting radiation. Cs atoms with atomic weights of 123, 125-132, and 134-145 are radioactive cesium isotopes. (12 Dec 1998) |
| cesium 137 | a radioactive isotope of cesium used in radiation therapy |
