ScienceRadiationGCSEAQA Created by: BelvastCreated on: 22-05-13 01:10 How do we describe the nuceli of a radioactive substance? Unstable 1 of 8 What is the name of the process that makes radioactive substances stable? Radioactive Decay. They emit radiation and turn into other elements. 2 of 8 Can we predict when an atom will decay? If not, why not? No – it is a random process not affected by external conditions. 3 of 8 What are the three types of radiation emitted? Alpha radiation, beta radiation and gamma radiation 4 of 8 Which part of an atom might emit alpha particles? Nucleus 5 of 8 What is background radiation? The radiation surrounding us 6 of 8 Where does background radiation come from? (3) Environment, space, devices such as x-ray tubes 7 of 8 What happens to the rate of radioactive decay when the temperature is doubled? It stays the same 8 of 8
