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.
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.
| Feature | Benefit |
|---|---|
| Wearable Wristwatch Design | Always-on-body monitoring; lightweight (< 70 g) and compact (Φ45 mm × 20 mm) for all-day comfort |
| Energy-Compensated GM Tube | High-sensitivity detection with strong anti-interference; accurate across 50 keV – 1.3 MeV |
| Large Backlit LCD Display | Extra-large fonts for easy readability in any lighting; real-time dose rate, cumulative dose, and working time displayed |
| Triple Independent Alarms | Audible and visual alarms for dose rate, cumulative dose, and working time — all thresholds continuously adjustable |
| USB Data Transfer | Built-in storage with USB connectivity for downloading dose records; enables long-term tracking and regulatory reporting |
| Ultra-Low Power | < 2 mW consumption ensures extended battery life for full-shift monitoring |

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.
The CESSTEN GM-16 Wearable Radiation Dosimeter is available for immediate order:
Custom configurations — including modified dose rate ranges, tailored alarm thresholds, OEM branding, and specialized packaging — are available upon request. Contact CESSTEN for a tailored quotation and technical consultation.
