Properties of radioactivity
WebProperties of radiation. Alpha radiation. Alpha radiation is the least penetrating. It can be stopped (or absorbed) by a human hand. Beta radiation. Gamma radiation. WebWhen a radioactive atom emits an alpha particle, the original atom’s atomic number decreases by two (because of the loss of two protons), and its mass number decreases by four (because of the loss of four nuclear particles).
