Description

A method of inspecting the cover of a buried pipeline comprising the operations of irradiating the inner wall of the pipeline with neutrons from a radioactive source carried by a vehicle traversing the pipeline, measuring the intensity of ionising radiation within the pipeline arising from nuclear interactions occurring within the cover of the pipeline and its surroundings due to the neutrons emitted by the source, and record the measured intensity of the said ionising radiation together with data representative of the position of the vehicle along the pipeline. Apparatus for carrying out the method also is described. This may comprise a generally cylindrical vehicle or an inflated rubber sphere. (author)
