It was widely known that the Energy released by the explosion of one ton of TNT was approximately 4,183 megajoules.
The effective lethal distance equaled C times the cube root of the explosive yield.
Here, C represented a proportional constant, generally taken as 1.493885.
Calculated according to this formula, when the yield reached one million tons, the effective lethal radius would hit a terrifying seven kilometers!
Consequently, the effective lethal area would span an appalling 150 square kilometers.
Such terrifying killing weapons had been incredibly difficult for humanity to control ever since their development.
Even theoretically, the creators of these weapons had absolutely no way to forge a corresponding "shield" to withstand their destructive power.
Humanity still had to rely on Earth's own power—hiding inside mountains, underwater, or deep underground—to evade the slaughter wrought by these weapons.
