摘要：

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