One answer only.    Even small quantities of radiation are very dangerous    All materials give off some radiation    Most of the radiation to which people are exposed comes from the nuclear industry    Very little is known about risks from radiation 6) Which country produces the largest share of the world's uranium, the basic fuel for the generation of nuclear electricity? One answer only.    Australia    Canada    Russia    UK 7) How many countries generate electricity using nuclear power? One answer only.    5    10    20    30 8) Which of the following statements is false? One answer only.    17% of the world's electricity comes from nuclear power    There are no new nuclear reactors under construction    Uranium is used as a counterbalance weight in aircraft    There was once a natural nuclear reactor on earth 9) Which two countries produced the greatest percentage of their electricity from nuclear power? One answer only.    Belgium + Sweden    France + Lithuania    Japan + USA    Switzerland + Ukraine 10) Which of the following statements about the waste fuel from nuclear power is false? One answer only.    Although radiation levels are high, the volume is small    After about 5 years it is about 1000 times less radioactive than when first removed from the reactor    It is to be stored indefinitely - there are no plans to dispose of it    After reprocessing it can be used again as a reactor fuel 11) Where are most countries planning to put their used nuclear fuel?
