Astatine (At): Properties & Uses - StudiousGu

Several groups of scientists believe that astatine-211 could be used to treat certain types of cancer. Radioactive Iodine 131 is already used to treat Thyroid cancers for example, because it preferentially accumulates in that organ Astatine. Astatine is a chemical element with the symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth's crust, occurring only as the decay product of various heavier elements. All of astatine's isotopes are short-lived; the most stable is astatine-210, with a half-life of 8.1 hours 211 Astatine is sometimes used as a radioactive tracer and in cancer treatment. Like iodine, it is known to accumulate in the thyroid gland. Like iodine, it is known to accumulate in the thyroid gland

Significance and Uses. The only commercially important isotope of astatine is astatine-211. It is used in the diagnosis and treatment of various cancers. It is widely studied and used in nuclear medicine. Health Hazards. Astatine is not present in the environment that is why it poses no danger to human health Astatine is sometimes used as a radioactive tracer and in cancer treatment. Like iodine, it is known to accumulate in the thyroid glan Astatine is said to be more metallic than iodine, and, like iodine, it probably accumulates in the thyroid gland. Workers at the Brookhaven National Laboratory have recently used reactive scattering in crossed molecular beams to identify and measure elementary reactions involving astatine

Some researchers think that astatine will behave like iodine. If so, it could be used to treat certain diseases of the thyroid, such as thyroid cancer. When swallowed, the astatine would go to the thyroid. There, the radiation it gives off would kill cancer cells in the gland Mary McMahon Astatine has an atomic number of 85, and it is identified on the periodic table of elements with the symbol At. Astatine is a semimetallic chemical element classified among the halogens in the periodic table of elements

What is the element astatine used for? Study

Astatine is usually prepared according to the general equation: which indicates that bismuth -209 takes up one alpha particle and emits x neutrons to form an isotope of astatine, whose atomic weight depends on the number of neutrons lost. Metallic bismuth may be used as a target material Astatine-211 is sometimes used as a radioactive tracer and in cancer treatment. Like iodine , it is known to accumulate in the thyroid gland. Abundance and Isotope Astatine-211 is one such isotope that could be beneficial to alpha therapy because it has a longer half-life than traditionally used bismuth-213, and it can be produced in particle accelerators Uses: Similar to iodine, astatine may be used as a radioisotope in nuclear medicine, mainly for cancer treatment.The most useful isotope maybe astatine-211. Although its half-life is only 7.2 hours, it may be used for targeted alpha particle therapy. Astatine-210 is more stable, but it decays into deadly polonium-210 Crestor is used in adults to slow the progression of atherosclerosis (a build-up of plaque in blood vessels that can block blood flow). Crestor is used to lower the risk of stroke, heart attack, and certain other heart complications in men 50 years and older and women 60 years and older who have coronary heart disease or other risk factors

Astatine - Introduction, Structure, Uses, Health Effects

Astatine is one of the rarest chemical elements on Earth, and one of the most unstable. Nevertheless, it is of considerable interest to medical research as it could help destroy cancerous tumors that are difficult to treat. Mendeleev suspected its existence as early as 1869 Astatine has an important use in nuclear medicine, but it decays so quickly that it must be used within a matter of hours following production. Astatine concentrates in the thyroid and liver in a way similar to iodine, but it does not emit high-energy electrons like iodine does. Its short half-life makes it preferable to iodine for some treatments
