Shenzhen, China — August 2026 — CESTSEN, a leading manufacturer of radiation detection instruments, has officially launched the GM-16 Wrist-Worn Personal Dosimeter, a compact and high-precision device engineered for continuous X-ray and gamma radiation monitoring in professional environments. Combining the convenience of a wristwatch form factor with laboratory-grade measurement accuracy, the GM-16 redefines how radiation workers track their exposure throughout the workday.

Traditional clip-on dosimeters and pocket-style radiation badges are easily misplaced, forgotten, or left behind. The GM-16 eliminates this risk by integrating a full-function personal dosimeter into a lightweight wristwatch design that stays on the body at all times during work hours. Weighing less than 70 grams and measuring just 45 mm in diameter, it offers continuous, unobtrusive monitoring without interfering with daily tasks.
At the core of the GM-16 is an energy-compensated GM tube detector that delivers highly accurate measurements across a wide energy range of 50 keV to 1.3 MeV. The device measures dose equivalent rates from 0.10 μSv/h to 30 mSv/h and cumulative dose from 0.01 μSv to 9999 mSv, providing comprehensive coverage for occupational radiation protection.
