The Centers for Disease Control and Prevention (CDC) protects people’s health and safety by preventing and controlling diseases and injuries enhances health decisions by providing credible information on critical health issues and promotes healthy living through strong partnerships with local, national, and international organizations. įor more information on protecting yourself before or during a radiologic emergency, see CDC’s fact sheet titled “Frequently Asked Questions (FAQs) About a Radiation Emergency” at /radiation/emergencyfaq.htm, and “Sheltering in Place During a Radiation Emergency,” at /radiation/shelter.htm. Co-60 absorbed by the liver, kidneys, or bone tissue can cause cancer because of exposure to the gamma radiation.įor more information about Co-60, see the Public Health Statement by the Agency for Toxic Substances and Disease Registry at, or visit the Environmental Protection Agency at. Most Co-60 that is ingested is excreted in the feces however, a small amount is absorbed by the liver, kidneys, and bones. It resembles iron or nickel.īecause it decays by gamma radiation, external exposure to large sources of Co-60 can cause skin burns, acute radiation sickness, or death. This problem has been solved You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Co-60 can occur as a powder if the solid sources have been ground or damaged.Ĭo-60 is a hard, gray-blue metal. Cobalt-60 and iodine-131 are radioactive isotopes commonly used in nuclear medicine How many protons, neutrons, and electrons are in atoms of these isotopes Write the complete electron configuration for each isotope. Co-60 also is a byproduct of nuclear reactor operations, when metal structures, such as steel rods, are exposed to neutron radiation.Ĭo-60 occurs as a solid material and might appear as small metal disks or in a tube, enclosed at both ends, that holds the small disks. Radioactive Co-60 is produced commercially through linear acceleration for use in medicine and industry. Nonradioactive cobalt occurs naturally in various minerals and has long been used as a blue coloring agent for ceramic and glass. Co-60 also is used for food irradiation, a sterilization process. of the 8,000,000 administrations per year of. An isotope of iodine is used for making tincture. These include iodine-131, cobalt-60, technetium-99m, iron-59, iron-55, cobalt-57, cesium-137, and zinc-65. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. Iodine 131 and cobalt 60 are used in medical sciences for the diagnosis and treatment of cancer and tumor. Radioisotope Brief Toxicological Profile Toxicology FAQs Polonium-210 plus icon. Mode of decay: Beta particles and gamma radiationĬhemical properties: Metallic solid that can become magnetically chargedĬo-60 is used medically for radiation therapy as implants and as an external source of radiation exposure.
