How toxic is cobalt-60?
Toxicity. Sustained exposure to Cobalt particles results in a type of lung fibrosis called “hard metal lung disease”. Cobalt-60 emits radiation, causing long-lasting symptoms like fatigue and hairloss, and even loss of consciousness.
What does cobalt-60 do to cancer cells?
Cobalt therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer. Beginning in the 1950s, cobalt-60 was widely used in external beam radiotherapy (teletherapy) machines, which produced a beam of gamma rays which was directed into the patient’s body to kill tumor tissue.
What are the benefits of using cobalt-60?
The advantages of Co/sup 60/ therapy over conventional x-ray therapy, stemming from the fact that in the lst instance energy absorption within the tissues is by the Compton effect and in the 2nd case by the photoelectric effect, are: (1) increased skin tolerance, (2) reduced bone absorption, (3) increase in depth dose.
What is the source of Cobalt-60?
of cobalt is cobalt-60 (Co-60). Cobalt-60 is a byproduct of nuclear reactor operations. It is formed when metal structures, such as steel rods, are exposed to neutron radiation.
What is Cobalt-59 used for?
Cobalt occurs naturally as only one stable isotope, cobalt-59. 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….Cobalt.
Why is Cobalt-59 stable?
Naturally occurring cobalt (27Co) is composed of 1 stable isotope, 59Co. The primary decay mode for isotopes with atomic mass unit values less than that of the most abundant stable isotope, 59Co, is electron capture and the primary mode of decay for those of greater than 59 atomic mass units is beta decay.
What kind of radiation can you get from Cobalt 60?
Co-60 is a hard, gray-blue metal. It resembles iron or nickel. How can it hurt me? Because it decays by gamma radiation, external exposure to large sources of Co-60 can cause skin burns, acute radiation sickness, or death.
What happens to the body when exposed to Cobalt 60?
Cobalt-60 absorbed by the liver, kidneys, or bone tissue can cause cancer from internal exposure to gamma radiation. Mishandling of a large industrial source of Co-60 could result in an external exposure large enough to cause skin burns, acute radiation sicknessradiation sickness A serious illness that can happen…
How is Cobalt 60 formed in nuclear reactors?
Cobalt-60 is a byproduct of nuclear reactor operations. It is formed when metal structures, such as steel rods, are exposed to neutron radiation. Beta Particles Beta Particle A form of particulate ionizing radiation made up of small, fast-moving particles.
What is the chemical symbol for Cobalt 60?
Radionuclide Basics: Cobalt-60 Cobalt (chemical symbol Co) is a hard, gray-blue metal that is solid under normal conditions. Cobalt is similar to iron and nickel in its properties and can be magnetized like iron.
