Abstract
A measuring device to be conveyed through an oil or gas pipeline at the bottom of the sea is provided for measuring the radioactivity of the surroundings along the pipeline. Thus, the support and/or the covering of the pipeline may be tested, the sea bottom sediments having an appreciably higher gamma radiation source strength than the sea water and the oil or gas which flow through the pipeline.
