Understanding Yttrium 90
Yttrium 90, also known as yttrium-90, is a radioactive isotope of yttrium with an atomic number of 39 and an atomic mass of 90. It is a beta emitter, meaning it releases beta particles, which are high-energy electrons that can be used to treat various medical conditions.
Yttrium 90 is a synthetic element, meaning it is not found naturally on Earth. It is produced through the bombardment of yttrium-89 with neutrons, resulting in the formation of yttrium-90.
Medical Applications of Yttrium 90
Yttrium 90 has several medical applications, including the treatment of certain types of cancer. It is used in brachytherapy, a type of internal radiation therapy where a small amount of radioactive material is placed inside or near the tumor to kill cancer cells.
One of the most common uses of yttrium 90 is in the treatment of thyroid cancer. It is used to destroy thyroid tissue that has spread to other parts of the body, such as the lungs, bones, or liver.
Yttrium 90 is also used to treat other types of cancer, including prostate cancer, breast cancer, and ovarian cancer. It is often used in combination with other treatments, such as surgery and chemotherapy, to achieve the best possible outcome.
Industrial Applications of Yttrium 90
Yttrium 90 has several industrial applications, including the production of phosphors for use in cathode ray tubes (CRTs) and other display devices.
It is also used in the production of luminescent materials, such as glow sticks and fluorescent paints.
Yttrium 90 is also used in the production of nuclear batteries, which are used to power small devices such as pacemakers and other medical implants.
Handling and Storage of Yttrium 90
Yttrium 90 is a highly radioactive isotope, and handling it requires special precautions to minimize exposure to radiation.
When handling yttrium 90, it is essential to wear protective clothing, including a lead apron and gloves, and to work in a well-ventilated area.
Yttrium 90 should be stored in a secure, radiation-proof container, and should be disposed of properly to prevent environmental contamination.
Comparison of Yttrium 90 with Other Radioisotopes
