gamma-gamma log: A "gamma-ray log" that records the intensity of induced gamma rays emitted by a subsurface formation as a result of gamma-ray bombardment. It is obtained by lowering into a borehole a source that emits gamma rays and a detector (shielded from the source) that receives signals indicative of the gamma rays scattered back to it from the surrounding rocks. 3, record 1, English, - gamma%2Dgamma%20logging

Le principe d'opération du carottage: rayons gamma-rayons gamma est généralement différent des techniques de carottage par radioactivité discutées précédemment. Le procédé de désintégration radioactive de la source change la charge du noyau sans changer le nombre de nucléons. 2, record 1, French, - carottage%20rayons%20gamma%2Drayons%20gamma
