L'invention a pour objet une méthode d'analyse d'au moins un crayon comprenant une colonne de combustible nucléaire, un crayon comportant des zones pleines emplies entièrement de combustible et des zones intermédiaires partiellement emplies de combustible, la méthode comprenant les étapes suivantes : acquisition (300) d'un profil de comptage associé à un isotope non migrant, un profil étant composé de mesures de spectrométrie effectuées le long du crayon pour cet isotope ; détermination (303) d'un ensemble d'au moins un indicateur K_i permettant de quantifier la diminution de matière au niveau d'une zone intermédiaire d'indice i, ledit indicateur étant déduit du profil de comptage ; détection (304) du changement de géométrie en comparant l'ensemble d'au moins un indicateur K_i à un ensemble d'au moins une valeur de référence RK représentative de la géométrie initiale de la colonne de combustible nucléaire.
摘要:
A microcontroller unit (3) measures and records a radiation exposure dose obtained from a detection output of a radiation detection unit (2), and when the radiation exposure dose or dose rate exceeds a predetermined threshold, issues a warning to the user by lighting or blinking a LED (4). The LED (4) is placed opposite a light-emitting/receiving element (62) of an electrical non-contact input device (6) provided on a display device (5), and is also used to transmit and receive recorded radiation dose data and a command or data transmitted from the non-contact input device (6). According to such a configuration, a portable radiation dosimeter that is compact and can manage the radiation exposure dose for a long term without placing a burden on the wearer can be realized.
