Abstract
Винахід стосується неорганічного матеріалу-сцинтилятора формули AnLnpX(3p+n), в якій Ln являє собою один або більше рідкісноземельних елементів, Х являє собою один або більше атомів галогену, вибраних із F, Сl, Вr або І, і А являє собою один або більше лужних металів, таких як К, Li, Na, Rb або Cs, n і р являють собою такі величини, що n може дорівнювати нулю, бути меншим або дорівнювати 2р, а р є більшим або дорівнює 1, причому вміст у ньому дочірніх елементів урану і торію є досить низьким для того, щоб зумовлена альфа-випромінюванням цих елементів активність складала менше від 0,7 Бк/см3. Цей матеріал має дуже низький радіоактивний фоновий шум і є особливо придатним для застосування як сцинтилятора детектора для вимірювань маси або товщини покриття або в галузях ядерної медицини, фізики, хімії і розвідки нафти, або при виявленні небезпечних або заборонених речовин.
