WebCesium (Cs, atomic number 55) is an alkali metal having 40 isotopes, ranging in mass from 112 to 151. Of these, the fission product cesium-137 (half-life 30.17 years) is of greatest concern. Cesium-137 is one of the nuclides most responsible for the radioactivity of used reactor fuel and high-level waste (with the other being strontium-90).

The number 222 indicates the atomic mass of the element (or isotope). WebCs-131 has a higher dose rate than I-125 (0.342 Gy per hour vs. 0.069 Gy per hour), translating to 90% Cs-131 dose absorption within 33 days of implantation, whereas only 32% of I-125 would be absorbed at this juncture. Cs-131's higher mean energy (29 keV) enables adequate dosimetry with the use of fewer seeds per given volume (33). how much should a cat weigh to get spayed
