    I’ve never understood this trend of having a bedroom boulder. My wife had to have a granite one too 😭

        what about this I woke up at 3 this morning and it’s my day off and don’t want to think enough to parse it. my brain is fucking tired. radiation is not my field.

        I just got the conclusion:

        This concentration is approximately one‐eighth the average radon gas concentration in U.S. homes (37 Bq m -3) and is well below the EPA guideline of 4 pCi L-1 (150 Bq m -3). This calculation is very conservative in that it assumes that there is no mixing of air between the kitchen and other rooms in the home. If air in the kitchen of the house flows easily into other rooms, then the radon‐222 concentration would likely be lower than the above calculation indicates. The kitchen area is assumed to be relatively large, as is the countertop area. In addition, the true emanation fraction for a solid granite slab is likely to be lower than the value of 0.1 used in the equation.

        which seems to say it’s generally a nonissue, just get a radon detector if you’re worried.

        That could also be mache. Otherwise my idea is that they discovered this during basement excavation and decided it was too expensive/difficult to move

      It’s likely an art project. Paper mache sort of thing.

      If I had to guess.

        If you look at the floor, you can see that the house was built around the rock. My bet is that they found the rock while digging out the basement. Options were $15,000+ to remove it, or $0 to just dig around it.

          There’s a fully painted wall behind it though. I see what you’re saying about the floor, but the wall behind it doesn’t really make sense either.
