单词	megaton
释义	megaton /ˈmɛɡətʌn / (also megatonne) noun A unit of explosive power chiefly used for nuclear weapons, equivalent to one million tons of TNT: H-bombs of fifteen megatons each... Were the asteroid to hit Earth, it would enter the atmosphere at nearly 103,000 km/h and strike with the explosive energy of 1.2 million megatons of TNT. The largest weapon of this kind known to have been tested was estimated to be a 58 megaton (58 million tonnes of TNT) device produced by the Soviet Union during the height of the cold war. Nearby in Balaclava (yes, the hat is named after this place - look it up), a submarine base is cut out of the side of a mountain, making it invisible to surveillance and able to withstand a 10 megaton nuclear explosion.
