It emits soft X-rays and that one orbital of light and neutrons when it fuses.These propagandists pretend that what is used now is pure fission weapons like in 1945 or u238 jacketed hydrogen bombs which could be up to 80 percent fission fraction due to the fast fissioning of the otherwise inert jacket. Of the 1950sAlso the initial frames of department of energy films are blanked out to hide yield and other exact figures such as the timing between stages.Neutron bombs are mostly fusion: X-rays and neutrons and one electron orbitals. This reduces the white flash: most of the light is from the air and bomb casing becoming plasma and emitting as a black body.
