The Atomtex AT 2503B/2 is a personal dosimeter engineered for reliable radiation monitoring across a wide energy range from 50 keV to 10 MeV. Designed for demanding environments, this compact device operates within temperatures ranging from -30°C to +60°C and withstands up to 90% relative humidity at 40°C. It is built to be shock and vibration resistant, complying with IEC standards and holding CE certification. In practice, the instrument measures a dose range from 1 μSv to 10 Sv and a rate range from 1 μSv/h to 10 Sv/h. For operational safety, it features eight independent, manually selectable alarm thresholds for both rate and dose, alongside a self-test function. The power system provides 1000 hours of continuous operation under normal conditions. With dimensions measuring 84x46x16 mm, the AT 2503B/2 offers precise measurement with a dose error of ±15% and a Cs 137 calibration error of ±5%.
