Recently, GRGTEST successfully passed the expansion review conducted by the China National Accreditation Service for Conformity Assessment (CNAS) and officially obtained the relevant qualifications on March 25. It has now acquired calibration capabilities for X-and γ-ray peripheral dose equivalent (rate) meters, personal radiation protection alarm devices, diagnostic level dosimeters, and neutron protection instruments, marking a new milestone in GRGTEST's service capabilities in the field of ionizing radiation.
Ionizing Radiation Laboratory
The newly recognized capabilities include 13 standards, such as JJG 393-2018 "Calibration Regulations for Portable X and γ Radiation Peripheral Dose Equivalent (Rate) Instruments and Monitors," JJG 912-2010 "Calibration Regulations for Therapeutic-Level Ionization Chamber Dosimeters," and JJF 1621-2017 "Calibration Specifications for Diagnostic-Level Dosimeters." To date, GRGTEST has accumulated a total of 42 CNAS-accredited calibration capabilities in the field of ionizing radiation (see the "Ionizing Radiation Calibration Capability Overview Table" for details).
