Billy121 Posted April 3, 2020 Share Posted April 3, 2020 Hello, I need some help from clever people. Regarding alpha, beta and gamma rays. If I was to shoot any of these at say a card of plastic is it possible to detect on the plastic that it had been shot with any of these? Using specialised camera perhaps? Would the rays leave a trace in any form? If not is it possible to shoot any type of rays or particles that would leave a trace on the surface of plastic at all, that Co ld be detected by a camera set up? Many thanks for all your wonderful help on this my friends. Link to comment Share on other sites More sharing options...
swansont Posted April 3, 2020 Share Posted April 3, 2020 It’s possible, but might require a large number of interactions to detect anything. High-energy electrons in a discharge leave tracks in plastic. They are called Lichtenberg figures. 1 Link to comment Share on other sites More sharing options...
studiot Posted April 3, 2020 Share Posted April 3, 2020 You might like to consider devising an experiment based on the response to streams of alpha, beta and gamma rays to electric/magnetic fields. http://www.passmyexams.co.uk/GCSE/physics/properties-of-radiation-magnetic-field.html Link to comment Share on other sites More sharing options...

MigL Posted April 3, 2020 Share Posted April 3, 2020 If plastics are your target of choice, most EMR, from visible light ,through x-rays, to gamma radiation will degrade plastics in the following manner... Discolor or yellowing effect Change in mechanical properties (varies by material) Crosslinking – increased tensile strength, decreased elongation Chain scission – reduced tensile strength and elongation from https://omnexus.specialchem.com/polymer-properties/properties/gamma-radiation-resistance In addition to the tracks made by beta radiation ( mentioned by Swansont ), this should give you the means to discern between the three types of radiation. 1 Link to comment Share on other sites More sharing options...
BabcockHall Posted April 10, 2020 Share Posted April 10, 2020 You might also ask which would pass through the plastic and which would not. Link to comment Share on other sites More sharing options...
