Beta particles are actually electrons (-e) or can be  positrons.The mass of one electron or beta particle is  9.1095*10-31 kilograms or  0.000548597 AMU which is about 1/20 â¦ 00 times the mass of a  proton or neutron.eta particles are actually electrons (-e) or can be  positrons.The mass of one electron or beta particle is  9.1095*10-31 kilograms or  0.000548597 AMU which is about 1/20 â¦ 00 times the mass of a  proton or neutron.
Protons and neutrons each have a mass of 1 atomic mass unit, and so an alpha particle has a total mass of 4. This high mass of an alpha particle explains how they interact with the human body. They are large and heavy particles and so tend to move slower than other kinds of dangerous radiation. However, because of their large mass, when they do collide with human tissue, they cause more damage.
