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
The treatment of cancer using cobalt-60 was pioneered by Canadian physician Dr. Harold E. Johns in the 1950s. Cobalt-60 is a radioactive isotope of cobalt that emits high-energy gamma rays, which can be used to target and destroy cancerous cells. Dr. Johns and his team at the University of Saskatchewan developed the first cobalt-60 therapy unit, revolutionizing cancer treatment worldwide.
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.
The only natural isotope of Cobalt is Cobalt-59.
Cobalt 60 is a very valuable radiation source for the treaments of many types of cancers.
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.

The "60" in Co-60 represents the atomic mass number of the cobalt isotope. It indicates that the cobalt nucleus contains 60 protons and neutrons combined.
