Particles and radiation

This topic can be tricky for students who have misconceptions around the particle model and is an ideal time to clarify this area, before building on it. It is important to use examples and models to show atoms and isotopes clearly and relate those to the effects on objects and cells. Students often also have other language from news reports and fiction that confuse them and cause misunderstandings like objects absorbing and becoming 'radioactive' themselves. This is why it is helpful to give several examples of real life uses and effects to show different scenarios like injecting tracers with a short half-life or using gamma radiation to sterilise equipment.       


Whilst this list provides a source of information and ideas for experimental work, it is important to note that recommendations can date very quickly. Do NOT follow suggestions which conflict with current advice from CLEAPSS, SSERC or recent safety guides. eLibrary users are responsible for ensuring that any activity, including practical work, which they carry out is consistent with current regulations related to Health and Safety and that they carry an appropriate risk assessment.
