1 Alpha radiation is a heavy, very short-range particle and is actually an ejected helium nucleus. 2  Some characteristics of alpha radiation are: 3  Examples of some alpha emitters: radium, radon, uranium, thorium. 4  Most alpha radiation is not able to penetrate human skin.

Properties of alpha, beta and gamma radiation. Alpha Particles. Alpha particles are strongly ionising but can be stopped by paper or skin. They have a strong positive charge (+2) and a mass of 4 (i.e. 4 times the mass of a proton). An alpha particle is in fact the same as a helium nucleus - 2 protons and 2 neutrons.Beta particles.Beta particles are electrons-but they are called beta particles to identify that they came from the nucleus of the atom.hey have a strong positive charge (+2) and a mass of 4 (i.e. 4 times the mass of a proton).
