WHAT IS IONISATION Ionisation has abilities that allow it to change a atom or a molecule (beta, gamma & alpha) into a ionising material. There are some cases where we are likely to find non ionising radiation (only in some objects for e.g.-) Ionizing radiation can consist of high speed subatomic (means smaller than or occurring with in an atom.)
It consists of 2 protons (+) 2 neutron s (-) Properties of alpha•Alpha particlesare relatively slow.•They have a lowpenetrating power•You can stop themwith just a sheet ofpaper. Alpha particles are•Alpha Particles relatively slow and heavyare heavier they are not much of a threat to the human body as it penetrates low power. As you can see here alpha is stopped by a sheet of paper
Beta is a free electron It also consists of fast movingProperties of Beta electrons• A positivelycharged betaparticle differsfrom an electron byhaving equal butopposite electricalproperties. A streamof beta particles iscalled a beta ray.•Beta rays are usedin equipment formeasuring andcontrolling thethickness of plasticfilms.•beta has themedium penetratingpower and themedium ionising•Beta can bestopped byaluminium.
Gamma consists of a very highProperties of Gamma electromagne tic radiation.•Gamma waves arewhat scientists useto keep food longer.•Gamma can causecancer•It can be anadvantage for ushowever it can alsobe a disadvantagein terms of theeffects it has on us.•They give out ahigh amount ofenergy it isextremelydangerous.•it can be stoppedby lead.
DIFFERENCE BETWEEN ALPHABETA AND GAMMA Demonstrate an understanding of the differences between alpha, beta and gamma radiation in terms of their ability. Alpha particle ionised more gas molecule in the cloud chamber than beta particles, producing more alcohol and water. A gamma ray is a packet of electromagnetic energy. Alpha, beta and gamma are all different (they are all ionising) however this is the only similarity that they differ.
DEMONSTRATE ANUNDERSTANDING THAT THEFOLLOWING ARE NON-IONISING Visible light Infar red Microwaves Radio waves I can demonstrate an understanding that the following at the top are non-ionising simply because they are all low energy waves that do not consist enough energy to knock of an electron.
