Water soluble fluors useful in enhancing images obtained in autoradiography have the general formula:

Water soluble floors

Water soluble fluor compositions

A method of stabilizing a solution of a radiolabeled compound comprising adding to such solution a compound having a substantially insoluble backbone, to which has been bound a quaternary ammonium group; or a water soluble primary, secondary or tertiary aliphatic amine. The present invention also includes a solution of a radiolabeled compound maintained in contact with such a compound, and as an article of manufacture, a sealed vial containing such a solution.

Method, composition and kit for stabilizing radiolabeled compounds

A liquid organic scintillation cocktail which is readily converted to a solid for disposal after use. Also disclosed are a method of disposal of radwaste employing the cocktail and a kit useful for practicing the method.

Liquid emulsion scintillators which solidify for facile disposal

A method and kit for stabilizing solutions of radiolabelled compound by the use of insoluble quaternary ammonium containing compounds. Also described are novel insoluble compounds having quaternary ammonium and sulfide groups for use in the present invention.
