A Neutron Bomb is a type of low-yield weapon of mass destruction, similar to the atomic bomb. However, there is a special difference between the two bombs: rather than using its blast to cause casualties, neutron bombs primarily use neutron radiation, using a thin casing that intentionally allows most of its radiation to escape. While an atomic bomb's power may be around 5% radiation, the power of a neutron bomb may be at least 40% reliant on radiation. Its strength also allows it to kill personnel within bunkers, tanks, and other conventionally protected structures.
