Radionuclide

Radionuclides (RN) are the general name for any radioactive isotopes that are used in medicine and science. RNs can be used for radiodiagnosis or radiation therapy, as well as for studying nuclear reactions.

One of the most common RNs is iodine-131 (131I), which is used to diagnose the thyroid gland. This RN emits gamma rays that can penetrate body tissue, allowing the doctor to see a tumor or other abnormality in the thyroid gland.

Another RN that is often used in medicine is technetium-99m (99mTc). This RN is used for radiation therapy of brain tumors. Technetium-99m emits beta particles that penetrate tumor cells and destroy them. This makes it possible to reduce the size of the tumor and improve the patient's quality of life.

In addition, launch vehicles are used in scientific research to study nuclear reactions and the properties of radioactive elements. For example, uranium-238 can be used to study the fission of uranium nuclei under the influence of neutrons.

Overall, RNs are an important tool in medicine and scientific research, and their use continues to expand with the development of new technologies and treatments.

Radioactivity is the ability of certain chemical compounds to transform into other substances, emitting different types of radiation: alpha, beta, gamma or x-rays. All these elements are radioactive and we all absorb them absolutely every day, when reading newspapers, books, watching TV
