Abstract

PURPOSE: To prevent radioactive substances or radiant rays from propagating in an optical cable by bending part of the optical cable at at least one point or more in a channel or corrugated shape, by providing a bulkhead inside of it and then by covering the circumference of the bulkhead with a layer that contains radiation shielding substances.
CONSTITUTION: After the sheath part of optical cable 1 is removed, channel-shaped or corrugated cylindrical lead pipe 2 is fixed between both ends of the cable sheath. Setting resin, such as epoxy resin and urethane resin, is injected into cylindrical lead pipe 2 and then hardened for airtight sealing. Radioactive substances are stopped and radiant rays from the radioactive substances can be prevented by the channel-shaped or corrugated cylindrical lead pipe provided at at least one point or more from transmitting in the longer direction of the cable.
