Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a luminescent article containing a phosphor-binder layer and a protective film adapted to it, e.g. a plate, a panel or a web. SOLUTION: This luminescent article contains a self-support or supported layer of phosphor grains dispersed in a binding medium and an adjacent protective film, and the protective film contains a binder and titanium dioxide as a white pigment. High-energy neutrons are emitted in a multiplication deceleration region formed with lead and beryllium by this method, low-energy neutrons are generated and radiated via a neutron multiplication reaction ((n, 2n) reaction), the number of neutrons is secured without being reduced even when a high-energy neutron source has a small output, and an expected nondestructive inspection can be made.
