Description

Automated gamma-ray spectrometry is a modern analytical technique used for radionuclide identification and quantification in environmental, industrial, and nuclear applications. This study presents the development and optimization of an automated gamma-ray spectrometry system using a high-resolution detector and advanced software for real-time spectral acquisition and analysis. Automated functions including energy calibration, efficiency correction, peak identification, and background subtraction were implemented to improve measurement reliability. The system reduces analysis time, enhances reproducibility, and minimizes operator-related errors. High sensitivity and precision were achieved for low-level radioactivity measurements. The automated approach also improves sample throughput for routine laboratory operations. Results indicate strong performance in radionuclide detection and activity determination. The system is suitable for environmental monitoring and waste characterization. It can also support radiological safety assessments. Applications in nuclear research and quality control are possible. Automation improves consistency between measurements. Overall, the developed system provides a reliable and efficient tool for modern gamma-ray spectrometric analysis.
