Permeability of caulking compounds to 222Rn.
Caulking compounds have been tested as 222Rn barriers. Of these, the most effective is GE acrylic Latex Silicone Caulk, 0.2 cm of which attenuates 222Rn by 98% to 99.9%. The same thickness of two commercial 222Rn barriers attenuates radon by 75% to 90%. Permeabilities range from 0.3 to 140 x 10(-8) cm2 s-1.
