In this video you will learn all the science for this topic to get a grade 9 or A* in your science exams!
Alpha particles are the most most ionising, followed by beta particles that are less ionising than alpha particles, but more ionising than gamma rays.
Alpha particles are the least penetrating are absorbed by a few centimetres of air or paper, whereas beta particles are more penetrating than alpha particles, but less penetrating than gamma rays. beta particles are not completely absorbed by paper, but beta particles are completely absorbed by 3mm of the metal aluminium. It takes metres of concrete or an extremely thick layer of the metal lead to absorb gamma rays.
Gamma rays have the greatest range, then beta particles, which have a range of a 1m in air, and finally alpha particles, which have the lowest range in air.
