It's not just Cesium 137. Of the 3000 or so known isotopes, MOST undergo radioactive decay. Only a fairly small percentage of the isotopes are stable. Usually, stability is achieved when the amount of neutrons, compared to the amount of protons, is "just right" - not too few, not too many. For the heavier elements (beyond lead), stability is no longer possible for ANY isotope.

What is the nuclear decay equation for cesium 137?
The equation for the beta decay of 137Cs is: 55137Cs --> 56137Ba + -10e where the -10e is a negative beta particle or electron.
What is the nuclear decay equation for cesium-137?
The equation for the beta decay of 60Co is: 2760Co --> 2860Ni + -10e where the -10e is a negative beta particle or electron.
What particles come out of radioactive decay?
The primary particles emitted from radioactive decay are alpha particles and beta particles.Alpha particles are helium nuclei, two protons and two neutrons.Beta particles comes in two flavors. In Beta- decay a neutron is converted into a proton, resulting in a W- boson, which then nearly immediately decays into an electron and an electron antineutrino. In Beta+ decay, a proton is converted into a neutron, with the emission of a positron, and an electron neutrino.Sometimes, more than just alpha particles are emitted, in a process called cluster decay, of which alpha decay is simply a subset. You can have multiple alpha particle emission, or you can have substantially larger particles emitted, such as the nuclei of Cesium-137, as a result of fission. While fission is normally an induced process, in nuclear reactors and bombs, it can also spontaneously occur, so it can also be called a decay process.Another particle that can be emitted during fission, spontaneous or induced, is the neutron. Under the right conditions, these neutrons can go on to induce further fission, in a process we call a chain reaction. Controlled, we call that a nuclear power plant; uncontrolled, we call that a bomb.Last, there is gamma radiation or x-rays. Most decay processes leave the nucleus or electron cloud in an excited state, and it "wants" to lose its excess energy and return to normal state. When this happens, a photon is emitted, resulting in gamma radiation (nucleus) or x-rays (electron cloud) of various energies. Most of the time, this photon emission occurs very quickly, on the order of 1 x 10-12 seconds after excitation, but some nuclei, such as Technetium-99m, have a meta-stable state that allows them to stay excited for a long time, usually minutes or hours.
Fender STRAT serial number E022671 when made?

What are piano exam scores?
Piano exam scores are scores depending on how well you played in your exam the perfect score is around 137.
When cesium-137 undergoes beta minus decay what new element is formed?
Cs-137 decays to become the metastable element Ba-137m which has a half-life of only 2 minutes 55 and then it eventually becomes Barium-137. The nucleus undergoes a transition in which one of the neutrons becomes a proton which moves it up on the periodic table one place to become Barium-137. During this process is gives off a photon (gamma) with an energy level of approximately 662 keV.
What is the parent radioisotope if a beta decay produces barium-137?
Cesium-137
Is Cesium a radioactive element?
Only one naturally occurring isotope of cesium is known, cesium-133 (133Cs) which is not radioactive. A number of artificial radioactive isotopes of cesium are known also. One radioactive isotope of cesium is of special importance, cesium-137. It is produced in nuclear fission reactions. Read more on cesium in the link below.
What is the half life of cesium 137?
The half-life of cesium-137 is about 30 years. This means that it takes 30 years for half of a sample of cesium-137 to decay into a more stable element.
Can cesium 137 be dissolved by chlorine?
Cesium-137 will react with chlorine to form cesium chloride. However it is highly radioactive so must be handled carefully, because of this it is often used to treat cancer patients and sterilize medical equipment and some foods.
What is the parent radioisotope if a beta decay produces barium 137?
Same mass, atomic number one lower - Cs - caesium
Why does cesium-137 undergo radioactive decay?
It's not just Cesium 137. Of the 3000 or so known isotopes, MOST undergo radioactive decay. Only a fairly small percentage of the isotopes are stable. Usually, stability is achieved when the amount of neutrons, compared to the amount of protons, is "just right" - not too few, not too many. For the heavier elements (beyond lead), stability is no longer possible for ANY isotope.
Does intracavitary radiation use cesium?
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.
What is the symbol for cesium 137?
137Cs55 is the symbol for cesium 137.
What is the result of cesium-137 undergoing beta-minus decay?
Beta minus decay emits a positron so a proton is changed to a neutron in this process. This means that caesium 137 decays to Xenon 137
What was the radioactive source in the Goiania accident?
The radioactive source in the Goiania accident was cesium-137, which was found inside a radiotherapy machine that was scavenged from an abandoned hospital. When the machine was dismantled, the cesium-137 was removed and spread throughout the surrounding area, leading to widespread contamination.
What is the mass number for cesium?
The standard atomic weight for cesium is 133. There are 3 other radioactive cesium isotopes that have atomic weights of 134, 135, and 137. Cesium 133 is the only one that is found in nature. The other isotopes are synthetic.
