What is the definition of background radiation?
Background radiation is the low-level radiation that is naturally present in the environment, originating from sources such as cosmic rays, rocks, and radon gas.
What is a half-life?
A half-life is the time it takes for half of the nuclei in a sample of a radioactive isotope to decay.
What is the difference between nuclear fission and nuclear fusion?
Nuclear fission is the splitting of a large nucleus into smaller nuclei, while nuclear fusion is the combining of two small nuclei to form a larger nucleus.
Name two types of nuclear radiation.
Alpha radiation and beta radiation.
What is meant by 'random nature of radioactive decay'?
The random nature of radioactive decay means that it is impossible to predict when a particular nucleus will decay, though the overall decay rate of a sample can be calculated.
What are the main uses of nuclear radiation in medicine?
Nuclear radiation is used in medical imaging (e.g., PET scans), cancer treatment (radiotherapy), and sterilisation of medical equipment.
Write the nuclear equation for the decay of carbon-14 (C-14) to nitrogen-14 (N-14).
$\text{C-14} \rightarrow \text{N-14} + \beta^-$
What is the charge and mass of an alpha particle?
An alpha particle has a charge of +2 and a mass of 4 atomic mass units (amu).
Why do radioactive materials emit radiation?
Radioactive materials emit radiation as unstable nuclei decay to become more stable.
How is nuclear fission used in power plants?
In power plants, nuclear fission is used to generate heat, which produces steam to drive turbines and generate electricity.
