In all three periods , less than two-thirds of the samples showed agreement within a factor of 2 , and more than a quarter showed a difference greater than a factor of 3 . The risk may be greater in some cases , less in others ; but it is always present in sufficient measure to render the use of nuclear weapons unacceptable to the international community in all cases .
