Which energy component accounts for about 15% of the detonation energy as various forms of radiation?

• A. Blast/Shock
• B. Thermal Energy/Radiation
• C. Electrical Energy
• D. Nuclear Radiation

Answer: (D)

Energy released in a detonation splits into several channels: a large portion goes into the blast wave, another portion heats the surroundings and radiates as thermal energy, and a smaller portion escapes as radiation produced directly by the nuclear reactions. That radiative portion—nuclear radiation—includes prompt gamma rays and fast neutrons emitted during the reaction, and it typically amounts to about a fifteenth of the total energy. So the best label for this radiative fraction is nuclear radiation, since it comes specifically from the nuclear processes rather than from the mechanical blast or the general heat of the fireball. The blast/shock describes the mechanical energy of the expanding medium, and thermal energy/radiation covers the heat and infrared radiation from the fireball, while electrical energy isn’t a primary channel in this context.
