Claim 1

In a method for the disposal of low-level radio-active wastes by encapsulation of the radio-active waste within a hardenable resin, the steps of the method comprising providing a disposable container and an agitator selectively disposable within the container and external to the container, the container having a generally open upwardly-facing end, adding to the container a pre-determined quantity of hardenable resinous material and radio-active waste, agitating the mixture of hardenable resin and radio-active waste until the radio-active waste is encapsulated within the hardenable resin, closing the open end of the container during the mixing process with a container cover, the container cover being maintained in a generally fixed relationship to the agitator, the container cover having a disposable splash guard generally adjacent to the disposable container, subsequently removing the agitator from the container, permitting the contents of the container to harden and transporting the container to an approved disposal site, the improvement which comprises providing a generally annular membrane partially closing the open end of the disposable container and permitting passage of the agitator therethrough, the membrane being deflected by and generally conforming to the splash guard, the membrane serving to reduce the amount of resin and radio-active material splashing directly on the splash guard.
