What are the similarities between alpha ray beta ray gamma ray?
The only similarity is that they are all a form of radiation. Alpha is not a ray. It is a Helium nucleus, two protons and two neutrons. Beta is not a ray. It is an electron. Gamma is a ray. It is energy, no particle, no mass, just a form of light called a photon. Each of these forms of radiation has its own way of being dangerous.
