γ-rays: γ-rays are high-energy photons emitted during radioactive decay or nuclear reactions. They have no charge and are similar to X-rays but with higher energy. Cobalt-60 is an intense source of γ-rays. It is commonly used in medicine for radiation therapy and imaging. 

α-particles: α-particles are helium nuclei consisting of two protons and two neutrons. They have a positive charge and are relatively large and heavy. Cobalt-60 is not a source of α-particles. 

β-particles: β-particles are high-energy electrons or positrons emitted during certain radioactive decays. They have a negative charge and are much smaller and lighter than α-particles. Cobalt-60 does not emit β-particles. 

γ-rays: γ-rays are high-energy photons emitted during radioactive decay or nuclear reactions. They have no charge and are similar to X-rays but with higher energy. Cobalt-60 is an intense source of γ-rays. It is commonly used in medicine for radiation therapy and imaging. 

Neutrons: Neutrons are subatomic particles with no charge and a mass similar to that of a proton. They are not emitted by Cobalt-60.
