how can the risks of contamination of radiation be reduced?
the damage of radiation contamination to health depends on what things?
what does high doses of radiation increase the risk of?
what is radiation measured in?
what is half life?
can it be predicted when a nucleus will decay?

what is radioactivity measured in?
where does background radiation come from?
give examples of where background radiation can come from?
why does radiation cause health problems?
what form of radiation is more dangerous inside the body?

how does nuclear fission work in a nuclear power station?
describe the process of nuclear fission
what reaction happens in nuclear fission?
how is the chain reaction controlled in nuclear fission?
why does the chain reaction in nuclear fission need to be controlled?
what is nuclear fusion?

what happened in 1989 with the scientists that claimed they achieved cold fusion?
what cant happen in nuclear fusion and how is this avoided?
how is low level nuclear waste disposed of?
how is intermediate level waste disposed of?

when is a black hole formed?
what is the 'plum pudding' model of the atom suggest?
what did Rutherford, Marsden and Geiger's alpha particle scattering consist of?
some of the alpha particles passed straight through the gold foil, what did this show?
some alpha particles were deflected at small angles what does this show?
some alpha particles were deflected at very large angles what does this suggest about the nucleus?
