  • Use of nuclear and radiological weapons by terrorists?

    The hurdles for terrorists to get a nuclear weapon are extremely high. The probability of terrorist use of such a weapon is therefore extremely low. In contrast to the nuclear weapon case there are in principle no insurmountable obstacles to the acquisition and use of radiological weapons by a well-organized terrorist group, even though such an action remains high-tech and thus very difficult.
