Neutron bomb

A neutron bomb is a type of nuclear weapon that does not cause a large explosion like most nuclear weapons. Instead, a neutron bomb releases a burst of radiation when it explodes. This radiation can kill people quickly and is deadly even after the explosion. The radiation doesn't last for very long, so the bomb does not cause lasting environmental damage. While it can kill many people quickly, a neutron bomb is only effective in a very small area, and doesn't cause much destruction in the surrounding areas.
