Scenario 6   (Instructions) 1) Which statement regarding the immediate effects of a 1 kiloton burst of an improvised nuclear device is not true? Radiation energy is released in greater percentages than blast and heat. People located greater than one mile from ground zero are likely to have no immediate health effects from radiation. An electromagnetic pulse (EMP) could disrupt function of electronic devices. Fallout will result if the IND is a ground surface burst, as opposed to an air burst. Third degree burns may result within an approximate radius of one-half mile.
