The Rock in My Room
The collection never grew to a large proportions, most of the pieces wait in cardboard boxes for their fate. Some of the bigger, crystallized minerals are still in my room. Objects which remind me off all the weird hobbies I've taken on and abandoned eventually.
I had an idea today. Let's test if any of the rocks has detectable radioactivity over the background radiation. Oh yes. It's good to have all those expensive and exotic measuring devices in a common household. Of course it is quite ironic not to find a measuring tape in your home, but to have a frequency counter, radio scanner and a dosimeter within an arm's reach...
So anyways - I've found out that I kept a rock with four times the normal background radiation in my rooms. The close reading (beta plus gamma radiation) gives around 0.47 uSv... (where u=micro) Hey, I would not really want to keep that under my pillow.
Radioactive rock? Anyone? Check out the very short video. The beeping is coming from the dosimeter, of course safety standards would be badly crossed with that kind of long time exposure:
