A technique for measuring the U [uranium] or Pu [plutonium] concentration in solutions by determining the ratio of the transmission of photons whose energies closely bracket the K-electron absorption edge of the U or Pu. 1, record 1, English, - K%2Dedge%20densitometry
Record number: 1, Textual support number: 1 OBS
Hybrid instruments combining K-edge densitometry and X ray fluorescence analysis are used for determining U and Pu concentrations in mixed solutions, including highly radioactive spent fuel solutions. 1, record 1, English, - K%2Dedge%20densitometry

[…] les EUTU [uranium et éléments transuraniens] sont un cas favorable d’application de l’absorption puisque celle-ci croît avec le numéro atomique Z. [L'appareillage en question] est développé suivant ce principe. La source de rayonnement est un tube X alimenté à 150 kV [kilovolts] et 15 mA [milliampères]; la mesure est faite au moyen d’un détecteur au germanium intrinsèque à haute résolution. Les discontinuités K des actinides se situent dans la zone des 100 keV [kiloélectronvolts]. 2, record 1, French, - densitom%C3%A9trie%20%C3%A0%20spectre%20d%26rsquo%3Babsorption%20K
