| titleOfInvention | Method and apparatus for radioactive well logging |
| abstract | A radiation source for use in radioactive well logging and logging methods employing such source. The source comprises emitter and target components which are movable relative to one another. Both components may take the form of concentrically disposed inner and outer casings or sleeves. Each component includes a plurality of laterally spaced surfaces with those of the emitter component containing an emitter material and those of the target component containing a target material which is characterized by the emission of primary radiation in response to exposure to radiation from the emitter material. Means are provided for moving the emitter and target components to an active position in which complementing surfaces are adjacent one another to provide for the emission of primary radiation and an inactive position in which the surfaces are displaced longitudinally from one another. |
