<p>A method for determining the position of a leak in a conduit or pipeline, especially one of small diameter, in which a carrier body (6), for example a short length of co-axial cable (7), carrying a short-lived radioisotope is inserted into the conduit or pipeline and is caused to move along it by pressuring up the conduit or pipeline from one or both ends (10, 11) thereof with fluid, for example water. The carrier body (6) travels to the leak (12) but no further and its location is detected from outside the conduit or pipeline using a radiation detector.</p> |
