Radiation 3.0 / 5 based on 1 rating ? PhysicsRadioactivityGCSEOCR Created by: Kieren James SaddlerCreated on: 12-04-15 12:42 What are the properties of Alpha radiation? Slow and heavy 1 of 16 What releases Alpha radiation? Very heavy nuclei (e.g. uranium) 2 of 16 What is an Alpha particle? A helium nucleus (2 protons & 2 neutrons) 3 of 16 What is the mass and charge of Alpha radiation? Mass of 4 and charge of +2 4 of 16 What does Alpha decay always do? It changes the element of the decaying atom (it is losing protons) 5 of 16 What is Beta radiation? Lighter and more penetrating 6 of 16 How are they released? By nuclei that have too many neutrons 7 of 16 What does a neutron turn into and what happens as a result? A proton. The element changes 8 of 16 What is Beta radiation identical to? An electron 9 of 16 What is Gamma radiation? An electromagnetic wave with no mass 10 of 16 What conditions would have to exist for Gamma radiation to be produced? The nucleus still has extra energy after emitting Alpha or Beta radiation 11 of 16 What does a Gamma ray have? No mass 12 of 16 If Gamma radiation is just energy, what does/does not happen? It does not change the element 13 of 16 What blocks Alpha radiation? Paper/skin 14 of 16 What blocks Beta radiation? Thin aluminium/any metal 15 of 16 What blocks Gamma radiation? Thick lead/thick concrete 16 of 16
