Terbium is never found in nature as a free element, but it is contained. 3 : 39 It is produced artificially in nuclear reactors. The ninth member of the lanthanide series, terbium is a fairly electropositive metal that reacts with water, evolving hydrogen gas. Cobalt-60 (60 Co) is a synthetic radioactive isotope of cobalt with a half-life of 5.2713 years. It is a silvery-white, rare earth metal that is malleable, and ductile. Cobalt-60 absorbed by the liver, kidneys, or bone tissue can cause cancer from internal exposure to gamma radiation. Terbium is a chemical element with the symbol Tb and atomic number 65. Cobalt is a chemical element, lustrous silvery-gray ferromagnetic transition metal of Group 9 (VIIIB) of the periodic table with atomic number 27 and symbol Co. Most Co-60 that is ingested is excreted in feces however, a small amount is absorbed by the liver, kidneys and bones. Cobalt and Healthīecause it decays by gamma radiation, external exposure to Co-60 can increase cancer risk. Such exposures are carefully controlled to avoid adverse health impacts and to maximize the benefits of medical care. Most exposure to Co-60 takes place intentionally during medical tests and treatments. Though relatively rare, exposure has also occurred by accidental mishandling of a source at a metal recycling facility or steel mill. Accidental exposures may occur as the result of loss or improper disposal of medical and industrial radiation sources. It is also used for radiation therapy in hospitals. ![]() Cobalt-60 is used as a radiation source in many common industrial applications, such as in leveling devices and thickness gauges. Cobalt (pronunciation: KO-bolt) is a hard, lustrous silvery-blue element belonging to the group of transition metals, and it is represented by the chemical.
