CESSTEN Unveils GM-16 Wearable Radiation Dosimeter — Wristwatch X-Ray & Gamma Dose Monitoring
Shenzhen, China — CESSTEN announces the launch of the GM-16 Wearable Radiation Dosimeter, an innovative wristwatch-style personal radiation monitor engineered for professionals exposed to X-ray and gamma radiation in medical, industrial, and nuclear environments. The GM-16 redefines personal dosimetry by merging laboratory-grade measurement accuracy with the convenience of an always-on-body wearable device.
Precision Detection Technology
At the heart of the GM-16 lies an energy-compensated Geiger-Müller (GM) tube detector delivering reliable measurements across an energy response range from 50 keV to 1.3 MeV. This broad detection window covers common medical diagnostic X-ray energies, gamma emissions from radiotherapy sources (Cobalt-60, Cesium-137), and industrial radiography isotopes. The device measures dose equivalent rate Hp(0.07) from 0.10 μSv/h up to 30 mSv/h, with cumulative dose tracking from 0.01 μSv to 9999 mSv. With a relative intrinsic error of ≤ ±15% (¹³⁷Cs reference), the GM-16 meets international radiation protection accuracy standards.

Why the GM-16 Stands Out
Uninterrupted Compliance: The wristwatch form factor ensures the dosimeter is always on the wearer's body during work hours — no risk of forgetting a badge-style device. This continuous monitoring translates to more accurate occupational exposure records and stronger regulatory audit outcomes.
Triple-Layer Alarm Protection: Independent audible and visual alerts for dose rate, cumulative dose, and working time provide comprehensive safety oversight. All thresholds are continuously adjustable to match facility-specific protocols.
Data-Driven Safety Management: USB data transfer transforms the GM-16 into an active safety management tool. Dose records can be archived and analyzed to identify exposure trends, optimize shift rotations, and demonstrate ALARA compliance during inspections.
Certified Quality: CESSTEN instruments hold CE, CMA, and CNAS certifications. Each unit is individually calibrated and tested before dispatch from the Shenzhen manufacturing facility.
