Nobility is more than a state of mind. As it turns out, nobility also applies to a state of matter, namely, gas.
Radon is a noble, inert gas that decays quickly, sticking around for a couple days. This makes it one of the rarest naturally occurring noble gasses.
However, radon is off-gassed by thorium and uranium, which are very stable and common in Earth’s crust.
This means location plays the biggest role when it comes to how common radon is in the surrounding air.
Even if your indoor air seems fine, it might have radon seeping in through the tiny cracks in walls and the basement.
Having no color, smell or taste, radon quietly decomposes into radioactive particles that float inside homes.
To combat this, you may have considered getting an air purifier. But question is, do air purifiers really help with radon?
