Yes, intracavitary radiation can use cesium-137 as a radioactive source. cesium-137 is a common isotope used in brachytherapy for treating certain types of cancers.
Yes, interstitial radiation therapy can use radioactive isotopes of phosphorus, such as phosphorus-32, as a treatment for certain cancers. These radioactive sources are implanted directly into or near the tumor to deliver localized radiation therapy.
Patients receiving interstitial radiation do become temporarily radioactive
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.
Interstitial radiation therapy places the sources of radiation directly into the tumor and surrounding tissue.
The advantage is that it concentrates the radiation near the cancer and lessens the chance of damage to normal cells
Interstitial microwave thermal therapy is a type of hyperthermia treatment for cancer, in which heat produced by microwaves (which are a non-ionizing form of radiation) is used.

The threshold frequency of cesium is approximately 3.3 x 10^14 Hz. This is the minimum frequency of electromagnetic radiation required to eject electrons from the surface of cesium via the photoelectric effect.
