ABSTRACT:
This invention relates to a method for rendering a surface substantially impervious to alpha particle radiation such as that produced through radon decay. More particularly, the present invention involves applying to said surface an emulsion containing a sulfopolyester and a copolymer of vinyl acetate and dialkyl maleate, and a plasticizer. The sulfopolyester-acrylic copolymer blend produces a stable alpha particle radiation barrier on sand, rocks and soil.
