The potential dangers of nuclear weapons and the planned new breed of plutonium-fuelled reactors are the subject of An Unjustifiable Risk, made in 1977. John Pilger begins by explaining that just a speck of plutonium, the main component of an atomic bomb, can cause cancer, but there is no absolutely safe way of storing, protecting or transporting it. Although the government is planning to build the first commercial nuclear power station fuelled by plutonium – a so-called fast-breeder reactor intended to solve the country’s energy problems – an independent royal commission has declared the process dangerous.
