- Worried about radioactive contamination from a possibly used Geiger counter
I’m a mom and was worried about radiation in the new house we moved into, so I ordered a Geiger counter (the GQ gmc 500 plus) on amazon. But I noticed the screen protector film wasn’t pressed on all the way so there were some bubbles, there also was one scratch on the screen protector film and some scratches on the Geiger counter plastic itself, now I’m worried Amazon sent me a used product. Since amazon sometimes sells returned items as new. What if someone used it at Chernobyl or touched it to radioactive objects or materials and it’s contaminated? Now my hands my house my children are contaminated with radioactive materials? Also how do I know if it is radioactive or not? Also I bought it twice, the first one I bought had a stain on the manual and after placing the Geiger counter on the manual with the stains, it started reading a consistent 0.18-0.27uSv/hour. The second one I bought came scratched and it read around 0.12-0.15uSv/hour. Why did the first one I bought read higher after it touched the stained manual? Maybe the manual had radioactive contamination? Can a Geiger counter detect if itself is radioactive or has radioactive contamination?
