Specialist surgeons, medical oncologists, radiation oncologists, pathologists, radiologist.
Those are the ones in the medical industry.
When cobalt-60 emits a gamma ray, it remains as cobalt-60. The emission of a gamma ray does not change the identity of the cobalt-60 isotope.
No, cobalt-60 is a synthetic radioactive isotope of cobalt. It is produced by bombarding stable cobalt-59 with neutrons in a nuclear reactor.
Cobalt-60 has an 1/2 life of 5.24 years
Cobalt 60 has an extra neutron buit that does not affect chemical properties
Cobalt-60 decay to nickel-60:Co-60------------Ni-60 + 1 electron + 1 neutrino + gamma rays
Cobalt 60 is a radioactive chemical not usually available for sale. Cherolet manufactures the car Cobalt, which can accelerate from 0 to 60 mph in 5.2 seconds. Its cost is about $30,000.
I would not use Co-60 for shielding. Did you mean, "What is the half value layer for some shielding (XXXXXXXX) using Co-60 as a source of gamma ray energy?
The only natural isotope of Cobalt is Cobalt-59.
Since cobalt has an atomic number of 27, any isotope of it contains 27 protons and 27 electrons per atom. The isotope with mass number 60 contains (60 - 27) or 33 neutrons per atom.
Cobalt 60 is a very valuable radiation source for the treaments of many types of cancers.
In modern times, Cobalt-60 is the substance used to make self-luminous paint. Cobalt-60 has replaced Radium's use for the same applications due to Radium's radiation danger.
