Horizon: If terrorists ever attacked Trafalgar Square with a 'dirty bomb', the centre of London could possibly be left uninhabitable for more than 10 years. Using a specially commissioned scientific model, this programme demonstrates the devastation such an attack here : or on Washington DC's subway system : would cause, as experts reveal how easy such weapons are to manufacture, and discuss the health risks posed by nuclear fallout.
