La partie d'examen (1) comprend une section de rayonnement de rayons X (3) qui irradie le spécimen (TG) avec des rayons X (100), un capteur linéaire (4) qui détecte les rayons X (100) transmis à travers le spécimen (TG) qui est irradié avec ceux-ci par la section de rayonnement de rayons X (3), et une section de commande d'examen (6) qui identifie la gamme qui satisfait une condition prédéterminée concernant un dosage de rayons X transmis du spécimen (TG) sur la base d'un résultat de détection obtenu par le capteur linéaire (4). La partie de marquage (10) marque la gamme identifiée par la section de commande d'examen (6) sur le spécimen (TG).
