What Isotope Of Cobalt Is Radioactive?
cobalt-60.
cobalt-60, radioactive isotope of cobalt used in industry and medicine.
What cobalt is radioactive?
cobalt-60
The most common radioactive form of cobalt is cobalt-60. It is produced commercially and used as a tracer and radiotherapeutic agent. It is produced in a process called activation, when materials in reactors, such as steel, are exposed to neutron radiation.
Is cobalt-60 A radioactive substance?
Radioactive Co-60 is produced commercially through linear acceleration for use in medicine and industry. Co-60 also is a byproduct of nuclear reactor operations, when metal structures, such as steel rods, are exposed to neutron radiation.
Is cobalt 49 stable or radioactive?
4-10. Cobalt-59 is naturally occurring and is stable. Cobalt-50 through 58 and 60 through 75 are artificially produced and are radioactive.
Is cobalt-60 harmful to humans?
Like any radioactive material, it can also cause cancer if you’re exposed to low amount over a long period of time.
What happens if you touch cobalt-60?
Mishandling of a large industrial source of Co-60 could result in an external exposure large enough to cause skin burns, acute radiation sickness radiation sickness A serious illness that can happen when a person is exposed to very high levels of radiation, usually over a short period of time. or death.
Is all cobalt radioactive?
Cobalt-60 is a commercially important radioisotope, used as a radioactive tracer and for the production of high-energy gamma rays. Cobalt is the active center of a group of coenzymes called cobalamins.

Why is cobalt-60 unstable?
One of its synthetic isotopes, Cobalt-60 (Co-60), has an extra neutron in its nucleus that makes it unstable. As it breaks down, Co-60 emits high energy, “ionizing” radiation that can break molecular bonds.
Is cobalt-60 an unstable isotope?
Because of the unstable configuration of the atomic nucleus of cobalt-60, a neutron is changed to a proton and nickel-60 is obtained.
What is U 238 used for?
Depleted uranium (uranium containing mostly U-238) can be used for radiation shielding or as projectiles in armor-piercing weapons. Where does it come from? U-235 and U-238 occur naturally in nearly all rock, soil, and water. U-238 is the most abundant form in the environment.
What is Cobalt 57 used for?
Cobalt-57. Used in nuclear medicine to help physicians interpret diagnostic scans of patients’ organs, and to diagnose pernicious anemia.
What type of radiation does cobalt 57 emit?
γ-rays
1 PHYSICAL AND CHEMICAL PROPERTIES
The main radioactive isotopes 57Co, 58Co, and 60Co decay with respective half-lives of 272 days, 71 days, and 5.271 years, and emit γ-rays.
Is cobalt-60 a beta decay?
The cobalt-60 isotope undergoes beta decay with a half-life of 5.272 years. Cobalt-60 decays to Nickel-60 plus an electron and an electron antineutrino. The decay is initially to a nuclear excited state of Nickel-60 from which it emits either one or two gamma ray photons to reach the ground state of the Nickel isotope.
Is it safe to touch cobalt?
It can harm the eyes, skin, heart, and lungs. Exposure to cobalt may cause cancer. Workers may be harmed from exposure to cobalt and cobalt-containing products.
How much cobalt is toxic to humans?
* Exposure to 20 mg/m3 is immediately dangerous to life and health.
What is the most radioactive thing on earth?
radium
The radioactivity of radium then must be enormous. This substance is the most radioactive natural element, a million times more so than uranium.
How long does radiation from a cobalt bomb last?
The half-life of the radioactive cobalt produced is about 5 years, which is long enough to give the fallout plenty of time to settle before it decays and kills, but short enough to produce intense radiation for a lot longer than you’d last in a fallout shelter.
What happens if you swallow cobalt?
It may cause nausea and vomiting. However, absorbing a large amount of cobalt over longer periods of time can lead to serious health problems, such as: Cardiomyopathy (a problem where your heart becomes big and floppy and has problems pumping blood)
Is cobalt poisoning rare?
The development of systemic cobalt toxicity from hip arthroplasty appears to be very rare. Only 18 cases have been reported,28,30–37 ten involving MoM articulations.
Does cobalt-60 emit gamma rays?
Cobalt-60 emits two high energy gamma rays, making cobalt-60 both an internal and external hazard. The primary exposure pathways of concern are ingestion (drinking water and fish consumption), and exposure by inhalation and external exposure.
Is cobalt-60 Fissile?
Finally, it is also desirable that cobalt-60 is non-fissile, which means it cannot sustain the reactions necessary for radioactive material to be used in a nuclear reactor. The food industry would not work with an isotope that can be used for nuclear energy or weapons.
