gamma rays are rays of electro magnetic radiation relesed by the nucleas
nothing
same as alpha
8. how can beta radiation be useful
beta radiation can be useful due to the fact that it is moderatly penetarating
no way at all
in hospitals for xrays

10. how do alpha particals ionise things
because of there size they are strongly ionising , they collide into atoms and knock the electrons of them
alpha particals dont ionise anything instead they rise high up in the air like a helllium nuclei
11. how ionising are beta particles
not ionising in any way
beta particles are moderatly ionising
very ionising
12. how ionising are alpha particals
alpha particles are very ionising due to there size
not very
very because they have 2 protons and two neutrons
not very because they are like the helium nuclei
13. what are alpha particals
alpha particals can rise far up in the air, they are like helium howver they do contain the same atomic build up as the neuclius eg : 2 protons 2 neutrons
things that ionise electrons
alpha particals contain 2 protons and 2 neutrons, they are emitted from the nuclius however they do not go very far - they float like hellium but they bump into things and ionise them by knocking of the electrons, they will only rise a few cm before being
alpha particals do not cotain 2 protons and neutrons but instead one proton and 2 electrons
14. alpha particals summery
beta particles have virtually no mass and are used to detect thickness of metal as unlike alpha particles they wont dissolve right away. they penterate moderatly BPARTICLE before colliding into a material and are partially ionising
alpha particles - symbol a used in smoke alarms are fully absorbed by a sheet papaer and when they are emitted froma nucleus alpha radiation takes place they contain 2x protons 2x neutrons
not incorrect key fact B PARTICLE - they are super fast moving electrosna snd for every beta particle emitted a neutron particle has turend to a proton
no incorrect answer key facts - they have 2x neutrons 2 x protons in the nuclei and its like a hellium balloon they are often used in smoke alarms as they bind to ions and stop charge flow makeing the alarm go of
15. are alpha particals in anyway uselfull
alpha particles are used in day to day life in shops homes and school
alpha particals are usefull in xrays and when you go to the hospital aswell as in science experaments
yes, they are used in the home in smoke detectors, they ionise air particals casing a current to flow - if smoke is in the air alpha particals bind to the ions - the current stops and the alarm sounds
alpha particals are used in balloons
16. how do beta particles collied
they are absorbed by any other material than aliminium
beta particles penerterate moditeraly into materials before they collied
they silde into materials
17. how can beta emissions be useful
in no way at all
to test the varistion of thickness in the metal due to unlike alpha particles they are not absorbed quickly and immediatly so they can show variations in thickness of metals
in hospital xrays
18. what happens to the neutrons in the nucleous when the beta particals are emitted
for every beta particle emitted , the neutrons in the nucleus turn unto protons
