Cesium-134 has a half-life of 2.1 years and decays by emitting a beta particle. The relatively small amount of cesium-134 produced more than 20 years ago would essentially all be gone today due to radioactive decay. extent in soil. The three radioactive cesium isotopes identified above are produced by nuclear fission.
What type of radiation does cesium emit?
Beta Particles Type of Radiation Emitted: Beta Particles.
Does cesium emit gamma rays?
The most common radioisotope of cesium is cesium-137. It emits beta and gamma radiation, decaying to stable barium-137. Cesium-137 is widely used in gamma sources.
Is cesium a gamma?
), cesium-137 (US), or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons….Caesium-137.

What type of radiation does iodine-131 emit?
The most widely used iodine radioisotope, iodine-131, emits radiation in the form of medium energy gamma rays and beta particles, which disrupts molecules in cells and deposits energy in tissues, causing damage.
Is cesium harmful to humans?
Exposure to large amounts of radioactive cesium can damage cells in your body from the radiation. You might also experience acute radiation syndrome, which includes nausea, vomiting, diarrhea, bleeding, coma, and even death in cases of very high exposures.
Is Cesium 133 radioactive?
Cesium-133 is naturally occuring and is stable(2). Cesium-112 through 132 and 134 through 148 are artificially produced and are radioactive(2). Lide DR; CRC Handbook of Chemistry and Physics 86th Edition 2005-2006.
Is cesium toxic?
Nonradioactive caesium compounds are only mildly toxic, but the pure metal's tendency to react explosively with water means that caesium is considered a hazardous material, and the radioisotopes present a significant health and ecological hazard in the environment.
Is radioiodine therapy safe?
Radioactive iodine (RAI) is treatment for overactive thyroid (hyperthyroidism) and certain types of thyroid cancer. The term “radioactive” may sound frightening, but it is a safe, generally well-tolerated, and reliable treatment that targets thyroid cells so there is little exposure to the rest of your body's cells.
Why is iodine-131 used in radiotherapy?
Radioactive iodine treatment is a type of internal radiotherapy. It uses a radioactive form of iodine called iodine 131 (I-131). It is a useful treatment in thyroid cancer because the thyroid gland absorbs and stores most of the iodine in your body.
