As part of the IAEA technical support project for Turkmenistan, NRSC conducted an expert mission at the Central Chemical Radiometric Laboratory of the Civil Defense and Rescue Operations Directorate of Turkmenistan. The mission, led by Arpi Khachatryan, a leading specialist in Radiation Safety at NRSC, aimed to enhance occupational radiation protection, dosimetry, and calibration services in the Republic of Turkmenistan, following IAEA guidelines. The mission aimed first to strengthen the knowledge in radiation protection: to provide an in-depth overview of IAEA GSR Part 3 and GSG-7 recommendations on occupational radiation protection, emphasising external personal monitoring, dose assessment methodologies, and measurement techniques. Another goal was to improve dosimetry practices by reviewing Armenia’s experience, identifying strengths and areas for improvement, and ensuring that QA/QC processes align with international standards for accuracy and reliability. To enhance dosimetry System Operation, Armenian specialist offered a detailed overview of the Harshaw 6600 Lite System, including its components such as TLD 100 Dosimeters, calibration methodologies, and testing procedures to ensure proper functioning and maintenance of dosimetric equipment. Special attention was paid to Calibration Procedures: guiding the development of standard calibration procedures for dosimeter irradiation and reader calibration, ensuring traceability and consistency in dose measurements. NRSC expert also assisted their Turkmen colleagues in refining data reporting methodologies, introducing improved data recording and reporting practices aligned with international standards. Local laboratory personnel received hands-on training in WINREMS software for calibration and data acquisition, as well as in annealing and irradiation techniques, dosimeter reading, and calibration processes. The training also covered Cs-137 use for external irradiation and reader calibration. The NRSC remains committed to supporting international collaboration and capacity-building efforts to enhance radiation safety in alignment with global standards.
