Cesium Radioactive

Cesium is an element that can exist in several radioactive isotopes. The group of radioactive cesium isotopes includes isotopes with mass numbers from 123 to 144 and half-lives ranging from billionths of a second to 27 years. These isotopes have a wide range of uses, including diagnostic and therapeutic procedures.

One of the cesium isotopes widely used for medical purposes is cesium-137. It has a half-life of about 30 years, making it useful for radiotherapy and marriage therapy. Cesium-137 can be used to treat various types of cancer, including cervical, prostate and head cancer.

In diagnostics, cesium-131 ​​is the most common isotope of cesium. It has a half-life of about 8 days, which makes it possible to use it for the detection and study of various diseases and pathologies. Cesium-131 ​​is widely used in radioimmunotherapy and radionuclide diagnostics.

It is important to note that radioactive cesium isotopes can be dangerous and require special precautions when using them. All safety measures and appropriate protocols must be strictly followed to minimize the risk to patients and medical personnel.

Due to their radioactive properties, cesium isotopes have found application not only in medicine, but also in other fields. They are used in scientific research, industry and analytical chemistry. Cesium isotopes can be used as markers and indicators in various experiments and processes.

In conclusion, radioactive isotopes of cesium represent an important tool in medicine and other fields. Their use in the diagnosis and treatment of various diseases makes them a valuable resource in the fight for human health and well-being. However, the safety and proper use of these isotopes must be kept in mind to avoid unwanted effects and maximize their benefits.

Radioactive cesium is the common name for a group of isotopes so named for their long half-life of 2.5*10^4 years, and which contains variants with very different half-lives, from nanoseconds to millennia. The half-life is the time after which half of the radioactive atoms decay.

Cesium is radioactive along with other radioactive isotopes of cesium and can be used for a variety of purposes. The isotope, with a half-life of just 2.6 nanoseconds, is used in some medical procedures to target tumor tissue. For example, [iodine-131](https://en.wikipedia.org/wiki/Iodine-131), [strontium](https://ru.wikipedia.org/wiki/%D0%A1%D1%82% D1%80%D0%BE%D0%BD%D1%86%D0%B8%D0%B9) and [cesium-137](https://commons.wikimedia.org/w/index.php?title=File :Potassium_and_cesium_graphite_microsphere.JPG&uselang=ru) – for the treatment of thyroid, kidney, and intestinal cancer. Some radioactive elements from the cesium group, for example [sodium-24](https://www.imf.org/external/pubs/ft/fandr/amenu/24rus.htm), are used in industrial processes for water purification and atomic separation.

Article 4.16 of the Sanpin regulates the conditions for working with radioactive elements. Because cesium is an electropositive ion, it can be used in a variety of processes. It works in chemical reactions due to its high chemical activity and a large number of free electrons in a state close to the Fermi level. Typically, lead containers are used for storing and transporting cesium, since lead absorbs gamma radiation from radioactive cesium-220 and is a dense shielding material.
