Abstract

Dispositif pour l'étalonnage sur le terrain d'un appareil de diagraphie nucléaire 10 comportant un détecteur 14 de rayons gamma Ce dispositif comprend un manchon 40 dans lequel est réparti un matériau radioactif et qui est disposé autour de l'appareil de façon à entourer complètement le détecteur. Le gain de l'appareil est alors réglé pour donner une lecture déterminée. Application notamment à la détection de la radioactivité naturelle des formations.Device for the field calibration of a nuclear logging device 10 comprising a gamma ray detector 14 This device comprises a sleeve 40 in which a radioactive material is distributed and which is arranged around the device so as to completely surround the detector. The gain of the device is then adjusted to give a determined reading. Application in particular to the detection of the natural radioactivity of formations.
