A nuclear explosion itself is the thermal and radioactive emission from the nuclei being split or fusing together, where as the concussive force generated by it, in this case, is the shock wave generated by the growing fireball that heats and expands the surrounding air and creates a forceful disruption that acts as a blast. It is prefaced by a dip in pressure than a massive spike in it as the molecules in the air are all forced together into a not-wholly-invisible wall that pummels things in its path when it buffets them. The rest of the explosion, the thermal emission, heat and light, does the majority of the destructive impact, unlike conventional explosions. The radioactive emission, in the form of Gamma rays and Neutrons, tend to be particularly deadly as they are released at blinding speeds during detonation and are hard to defeat, whereas Alpha and Beta particles tend to be more a consequence of them clinging to atmospheric particulates that are created by the mushroom cloud and become fallout as the intense heat cools and they rain back to earth, either as "black rain" or just radioactive "snow", [@Luna_Maria]. I suppose this also constitutes a random fact about myself as well, that nuclear physics was a part of my repertoire. Unfortunately not often is that required but it certainly has been an interesting subject matter to delve into. I revisit it at times, when I become fond of learning things outside my actual scope or relevance.
