Definition - What does Neutron Embrittlement mean?
Embrittlement on its own is the loss of ductility in a material, thus making it brittle. This can have different mechanisms depending on the metal involved. Neutron embrittlement is caused by neutron radiation. It also causes the buildup of Wigner energy as well as neutron-induced swelling.
Neutron radiation does not ionize atoms like charged particles, because they do not have a charge. Neutron interactions have great ionizing power, and since they lack charge, their penetration is felt more than that of alpha or beta radiation. Gamma radiation is powerful, but neutron radiation can sometimes be more powerful than it.
