WebNuclear fission is the process of splitting atoms to generate energy. This type of energy is most commonly used in nuclear power plants to generate electricity for homes and businesses. Nuclear fusion is the process of combining two or more atoms to form a larger atom and releasing energy in the form of gamma rays and electromagnetic radiation. WebFission bomb radiation source. Most of the energy released by a fission bomb is in the form of x-rays. The spectrum is approximately that of a black body at a temperature of 50,000,000 kelvins (a little more than three times the temperature of the Sun's core). The amplitude can be modeled as a trapezoidal pulse with a one microsecond rise time ...
