FNIRSI Geiger Counter Nuclear Radiation Detector - Radiation Dosimeter With Lcd Display, Portable Handheld Beta Gamma X-Ray Rechargeable Radiation Monitor Meter, 5 Dosage Units Switched,0.0 Sv-500Msv

Works effectively as a radiation detector. Have used to check in house and surrounding areas around home and office. Helps keep peace of mind. Low battery consumption.

Easy to use

Beach sand can contain natural radioactivity from naturally occurring radioactive materials (NORMs) like uranium (238U), thorium (232Th), and potassium (40K). These materials can come from metamorphic and magmatic rocks that break down over time through weathering and erosion to form beach sand. The concentration of these materials can vary, and sands with smaller grains tend to have higher levels of activity

What was claimed is not provided, instead something else was there which is lower quality. See for yourself.

Working very poor

Very very bad product.. Not working properly..

No way to tell if it's accurate. But the radiation levels do change over time. So far the radiation levels are low.

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.

Very effective. My cat underwent radioactive iodine treatment, and I needed to protect myself. It's accurate and quick to detect. All my cat had to do was walk by or stand for any period of time. period of time.

Excellent
