Is cobalt-60 an atom?
cobalt-60, radioactive isotope of cobalt used in industry and medicine. Cobalt-60 is the longest-lived radioactive isotope of cobalt, with a half-life of 5.27 years. It is produced by irradiating the stable isotope cobalt-59 with neutrons in a nuclear reactor.
What is the number of protons and neutrons in cobalt-60?
Cobalt-60 has 27 protons (thus 33 neutrons). If an inter-nucleus neutron decays and emits an electron, this neutron transforms into a proton. Now we have 28 protons and 32 neutrons.
What is the name of Co-60?
of cobalt is cobalt-60 (Co-60).
What is the atomic number of cobalt?
27Cobalt / Atomic number
How many electrons does cobalt-60?
Cobalt-60 is composed of 27 protons, 33 neutrons, and 27 electrons.
What isotope is cobalt-60?
Cobalt-60 is an isotope that emits gamma rays essential to the medical community for cancer treatments, as well as sterilization of medical devices. Sterilization Cobalt-60 is the first and most widely used type of Cobalt-60.
How cobalt-60 is formed?
Cobalt-60 is artificially produced by bombarding a target material, either cobalt-59 or nickel-60, with neutrons. This reaction is produced by nuclear weapons detonations and in nuclear reactors. IS COBALT-60 HAZARDOUS? Cobalt-60 emits two high energy gamma rays, making cobalt-60 both an internal and external hazard.
What is the history of cobalt 60?
Cobalt was discovered by Georg Brandt, a Swedish chemist, in 1735. Brandt was attempting to prove that the ability of certain minerals to color glass blue was due to an unknown element and not to bismuth, as was commonly believed at the time.
What is Cobalts atomic mass?
58.933195 uCobalt / Atomic mass
How do you make a cobalt-60?
How many electrons does cobalt-60 have?
Is cobalt molecular or atomic?
Cobalt is an element with atomic symbol Co, atomic number 27, and atomic weight 58.93.
What is the absorbed dose constant of 60 CO2?
The absorbed dose constant is related to the decay energy and time. For 60 Co it is equal to 0.35 mSv/ (GBq h) at one meter from the source. This allows calculation of the equivalent dose, which depends on distance and activity.
How is 60 co formed in a nuclear reactor?
In the latter case (in the absence of added cobalt) the incidentally produced 60 Co is largely the result of multiple stages of neutron activation of iron isotopes in the reactor’s steel structures via the creation of 59 Co precursor. The simplest case of the latter would result from the activation of 58 Fe .
What is the chemical symbol for Cobalt 60?
Common Names: Cobalt-60 Atomic Number: 27 Chemical Form: Cobalt metal Chemical Symbol: Co-60 or 60Co Mass Number: 60 (33 neutrons) Physical Form: Thin cylinder of cobalt metal
Is co 60 harmful to humans?
Most exposure to Co-60 takes place intentionally during medical tests and treatments. Such exposures are carefully controlled to avoid adverse health impacts and to maximize the benefits of medical care. Cobalt and Health. Because it decays by gamma radiation, external exposure to Co-60 can increase cancer risk.
