1 Scope

GB/T 47010-2026 is the Chinese national standard covering the GAGG scintillator array - the ceramic that turns X-rays into light in a CT detector, with its light yield and decay time, its energy resolution, the afterglow that would smear an image, and the uniformity across an array of thousands of elements. First edition. It was issued on 28 January 2026 and has been in force since 1 August 2026, as a first edition. The document is under the responsibility of the Standardization Administration of China. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the product marking, technical requirements, inspection rules, labeling, and packaging for cerium-doped gadolinium gallium aluminum garnet polycrystalline scintillator arrays. The transportation, storage, and accompanying documentation describe the test methods. This document applies to cerium doping used in high-energy physics experiments, nuclear medicine imaging, security inspection, nuclear radiation detection, and industrial non-destructive testing. Production and inspection of gadolinium gallium aluminum garnet polycrystalline scintillator arrays.
