But the radiation levels do change over time. So far the radiation levels are low. Review: 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. ## Features - 【Nuclear Radiation Detector】FNIRSI GC-01 Geiger Counter Core Radiation Detector. Built-in GM sensor can detect gamma, beta, and x-ray Cumulative dose equivalent: 0.00uSv-500.0mSv; Energy range: 48 KeV-1.5 MeV ≤ plus minus 30% (at 137 Csgama) - 【Smart Alarm】3 modes: light, vibration, and sound. The Gaiager Counter can set the current dose alarm value and cumulative dose alarm values. Whether in sleep or active, the radiation monitor emits an alarm when the detected radiation exceeds the alarm threshold - 【MULTI-FUNCTIONAL GAYGER COUNTER】Our gigar counter has a variety of settings, such as alarm setting, system clock setting, unit setting, language changing, and can be operated in English(default) or Chinese. Easy one-handed operation - Operating principle: The FNIRSI GC-01 radiometer can be used as a probe to detect ionized radiation gamma, beta, and X-rays. The radiation ionization generates ion pairs and the ions are enlarged and converted to an electrical pulse count - Applicable Area: Widely used in environments where existing ionized radiation exists.
