How much radon penetrates through concrete?
Has anyone measured the penetration of radon gas through a concrete slab?
How much radon gets into a typical house through the concrete in the
basement or slab?
EPA publications write only about the radon pathway through openings or
cracks. They, however, explain that their sealing or caulking is not
effective. Soil gas and radon also penetrate through the pores in concrete.
And radon dissolved in water is carried indoors by moisture migration. I
wonder if there are some scientific data.
Your expert feedback and data will be greatly appreciated.
