The atomic bomb, which was developed secretly in the United States during World War II (WWII), differed from all earlier types of bombs. It contained radioactive substances that underwent very rapid changes under certain conditions, releasing immense quantities of light and heat. For an atomic bomb explosion, its radioactive constituents, largely an isotope of uranium called U-235 must be present in sufficient quantity, called a critical mass. The exact details of the bomb’s construction remain secret, but it probably contains two quantities of radioactive material that are brought together mechanically to form a critical mass and thus to explode. The other main type of nuclear bomb is hydrogen bomb, which is far more powerful than an atomic bomb, using isotopes of hydrogen. Ever since the development of hydrogen bombs in the 1950s, even scientists from other nations have made them smaller, improved their triggering mechanism and increased notably their explosive power, making it 45000 times as powerful as the bomb dropped on Hiroshima. In a future war, a hydrogen bomb would presumably be delivered to its target as the nuclear warhead of a guided missile.
It can be understood from the passage that ----.
