Neutron detection is a way of finding neutrons, which are tiny particles that have no electric charge. Neutrons are like little balls that are always bouncing around in the nucleus, or center, of an atom. Even though you can't see them, they are still there, and scientists can use special tools to detect their presence. The most common tool scientists use to detect neutrons is something called a neutron detector. This special tool is like a machine that has sensors that can "see" the neutrons and tell scientists they're there.
