  • Patent number: 4062099
    Abstract: A shield for a radiation piping rod is formed by shrinking a length of plastic resin tubing on a rod or on a mandrel having a portion conforming to a portion of the rod to be shielded. The shrunken tubing is provided with a lengthened slit to permit stripping from the rod or mandrel to form the shield. The shield is mounted on the rod after stripping, and an air interface is formed between the rod and the shield to minimize loss of radiation caused by the shield.
