K-edge densitometry: 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. 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. 3, record 1, English, - K%2Dedge%20densitometer

[…] 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%A8tre%20%C3%A0%20seuil%20d%26rsquo%3Babsorption%20K

Équivalent obtenu auprès d'un professeur de physique à l'Université de Montréal. Selon ce dernier, le terme anglais «K-edge absorption» qui a été soumis au service des consultations est mal tourné et il est préférable de parler du «side absorption K». 1, record 2, French, - seuil%20d%27absorption%20K
