Low level radioactive wastes containing cobalt-60 must be kept totally isolated from the environment for approximately 100 years, to allow them to effectively fully decay to nonradioactive products.
One way of doing this would be to:
Cobalt-60 decays by beta particle emission to highly excited isomers of Nickel-60, as these isomers relax to the ground state of Nickel-60 highly energetic gamma rays are emitted.
The decay equation is:Co-60----------------------Ni-60 + e-
Beta Particle
no, its not safe to dispose nuclear waste in water,rather it would be safe to dispose it in common salt trenches.

Cobalt-60
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.
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.
