No, cesium has no odor.
No cesium is a solid metal.
Cesium is extremely reactive.
It turns out that caesium-133 (or 133Cs or cesium-133, if you prefer an alternate spelling) is stable. It is the only stable isotope of caesium, and, as such, it won't be emitting any radiation under normal circumstances. Wikipedia has some particulars on caesium, and a link is provided.
Patients receiving intracavitary radiation do become temporarily radioactive
Internal radiation therapy
The advantage is that it concentrates the radiation near the cancer and lessens the chance of damage to normal cells
The CPT code 77762 Intracavitary radiation source application; intermediate.
Cesium 133 is the stable isotope of the family of cesium isotopes and thus has no nuclear radiation breaking out of its nucleus. The only radiation from cesium 133 would be an emission spectra data in the blue visible light zone with a few less intense lines across the visible spectrum.
One use of cesium is in atomic clocks.
The CPT code for intracavitary of the uterus depend on the application. There is simple, intermediate and complex.
Yes. Cesium is a live radiation souce that is used to treat a localized area. Chemo is a systemic therapy that courses through the entire body (it is not radioactive).
