A method for containing at least a portion of radioisotopes, radionuclides, heavy metal or combination thereof contaminating a substrate wherein a containment composition is applied to the substrate. The ingredients within the containment composition interact with the contaminants on the surface of the substrate until the containment composition has polymerized to a water insoluble form containing at least a portion of the contaminates enmeshed therein. The dried composition is removed from the contaminated surface removing with the composition at least a portion of the contaminate.
