  • Helically slit high-Z cable sheathing and method of using same
    Patent number: 4750805
    Abstract: A high-Z cable sheathing for shielding against ionic radiation includes tubes made of high-Z material having continuous helical slits extending from end to end of each tube. A helically cut tube made of polyethelene and lead provides a highly flexible sheath for surrounding one or more cables. One or more tubes create the layers of protection over the cable. Oppositely cut helically slit tubes are used adjacent to one another so that the slits of adjacent tubes do not become mechanically aligned with one another.
