Abstract
(EN)
The present invention provides an improved method for investing radioactive sources which takes into account variations in the materials potentially making up the samples. In particular, the invention provides a method of investigating radioactive sources in a sample, the method comprising detecting a portion of the emissions arising from the sample at an energy, the detected portion relating to a detected level, the detected level being corrected according to a correction method to give a corrected level at that energy. The invention also provides improved transmission sources and improved transmission based correction techniques for use in investigating radioactive sources in a sample.

L'invention concerne un procédé amélioré d'études de sources radioactives, dans lequel les modifications des matières constituant les échantillons sont prises en compte. L'invention porte notamment sur un procédé de recherche de sources radioactives dans un échantillon, qui consiste à détecter une partie des émissions provenant de l'échantillon à un certain niveau d'énergie, la partie détectée se rapportant à un niveau détecté, lequel est corrigé selon un procédé de correction, de sorte qu'un niveau corrigé soit produit, audit niveau d'énergie. L'inventions e rapporte encore à des sources d'émission et à des techniques de correction par émission améliorées, à utiliser dans la recherche de sources radioactives dans un échantillon.
