I've never understood this trend of having a bedroom boulder. My wife had to have a granite one too đ
What about radon and radioactivity in granite countertops?
Recently I came to know about this.
Edit: I should have added an explanation. It is only an issue when the ventilation is very low. Accumulation of Radon gas is the only thing to be worried about.
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 oneâeighth 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 radonâ222 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.
Aah I should have clarified more. My bad.
This is only an issue when the ventilation is very low, means when accumulation of Radon gas happens in some form. In spaces with ventilation it should not be a problem.
But Radon is "one of the leading causes of lung cancer, in non-smokers" . So not critical, but caution must be there is what I understood.
i guess don't put it in your basement
