RADTriage is the only dosimeter with right dose range to instantly triage the exposure for medical treatment and minimize panic & worry in an event of a radiological incident.

Wearable, reliable and fail proof (no moving parts or electronic). Sturdy, ready 24/7 without a battery, reader or maintenance.

Unaffected by ambient conditions such as sunlight, humidity, water, temperature and tamper resistant and temper evident.

【Nuclear Radiation Detector】FNIRSI GC-01 Geiger counter nuclear radiation detector with built-in GM sensor, fast response time and high accuracy, able to detect Gamma, Beta and X-rays. Cumulative dose equivalent: 0.00uSv-500.0mSv. Energy range: 48KeV-1.5MeV ≤ ± 30%（for 137Csγ)

【Smart Alarm】Enter the alarm setting option to set the current dose alarm value and the accumulated dose alarm value. Whether the detector screen is in sleep state or in operation,the radiation dose detected exceeds the alarm threshold,the radiation monitor will automatically alarm. Light/Vibration/Sound 3 combined alarm modes to choose.

【Multifunctional Geiger Counter】Our the geiger counter has other various setting, such as alarm setting, system clock setting and unit setting & language change,you can operate in English (default) or Chinese. Easy one-handed operation.
