The remainder of the delayed energy (8.8 MeV/202.5 MeV = 4.3% of total fission energy) is emitted as antineutrinos, which as a practical matter, are not considered "ionizing radiation."
Den resterende del af den forsinkede energi-udsendelse (8.8 MeV/202.5 MeV = 4.3% af den totale fissions energi) udsendes som antineutrinoer, der ikke betragtes som ioniserende stråling.
