## Description

Geiger Counter Nuclear Radiation Detector - Radiation Dosimeter with LCD Display, Portable Handheld Beta Gamma X-ray Rechargeable Radiation Monitor Meter, 5 Dosage Units Switched,0.0μSv-500mSv

Review: Seems good. - No way to tell if it's accurate. But the radiation levels do change over time. So far the radiation levels are low.
Review: Poor quality - Very poor quality product. Stopped working after I tried charging it.

## Features

- 【Nuclear Radiation Detector】FNIRSI GC-01 Geiger counter nuclear radiation detector with built-in GM sensor, able to detect Gamma, Beta and X-rays. Cumulative dose equivalent: 0.00 uSv-500.0 mSv. Energy range: 48 KeV-1.5 MeV ≤ plus/minus 30%（for 137 Csγ)
- 【Smart Alarm】3 modes of Light/Vibration/Sound. Geiger counter can set current dose alarm value and cumulative dose alarm value. Whether in sleep or active state, the radiation monitor will alarm if the detected radiation dose exceeds the alarm threshold
- 【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
- 【Working Principle】FNIRSI GC-01 radiation meter uses a trachea or small room as a probe to detect ionizing radiation gamma/Beta/X-ray. Radiation ionization generates ion pairs, ions are enlarged and converted into electrical pulse counts to measure
- 【Application Areas】Widely applied in the environment where existing ionize radiation. Such as home improvement radiation, geological survey, iron, Inspection vehicles, nuclear power plants, industry, radiology, radiology laboratories and so on

### ⭐⭐⭐⭐⭐ Review
*by R***R on 29 November 2025*

15 years ago I woked as a Forester in Northern WI. I got the opportunity to work inside the Enterprise Radioactive Forest (google this). A forest that the USFS experimented on with Cesium in the 1970's to help deterime what would happen if the big one ever happened and what the effects of radioactive fallout would be on our forest resources. The project ended decades ago, but the forest continued on. When I worked as a forester, I can say it was the most bizzare forest I ever worked in. The trees all grew weird, were stunted, or misformed. A lot had wires coming out of them from the experiment. I also found alunimum rods everywhere. I picked up one of these rods and used it as a walking stick during the project, and kept it as a momento of working on the project (nothing illegal, it was trash). Years later, I found it in my garage and kind of wondered, is this radio active? Seems logical that it could be. All reserch I did on transfering of radiation to metals like aluminum said it was unlikely, but I was curious so I bought this detector. Glad to find out that it wasn't and I could keep my momento. It actually did not register anything, while bannanas sure did.
