Remaining 15% of energy from detonation as various forms of nuclear radiation corresponds to which term?

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

Answer: (D)

When a nuclear detonation releases energy, it spreads into several forms: the majority becomes a blast/shock wave, a large portion becomes thermal radiation (heat and light), and a smaller portion remains as nuclear radiation. The term that describes energy released as ionizing radiation from the nucleus is Nuclear Radiation, which matches the remaining fraction described. Nuclear radiation includes particles and photons such as neutrons and gamma rays emitted during fission and from fission fragments. It’s not thermal energy (heat) or the blast wave (shock) or electrical energy, so those options don’t fit the indicated form of energy.
