Description General description Indium foil is widely used in nuclear facilities to capture thermal neutrons, because it shows a high cross section of neutron capture reaction. Hence, it may be used in dosemeters to measure exposure. Indium foils were studied for simultaneous monitoring neutron and photon intensities in a reactor core.
