Abstract

Le matériau de protection contre les rayonnements se rapporte aux équipements en contact avec les rayonnements; l'invention concerne plus particulièrement des matériaux de protection contre l'influence des rayonnements. Ce matériau comprend une matrice constituée d'au moins un composant ou une composition sur la base de ce composant autour de laquelle est disposée une charge se présentant comme un mélange polydispersé de ségrégation, constitué de particules métalliques et de leur mélange chimique. La masse globale de la charge dans le matériau, avec des paramètres prédéterminés tels que l'épaisseur et la masse, est déterminée sur la base des proportions en utilisant des valeurs obtenues par des méthodes connues de détermination du maximum de diffraction du passage de rayonnement à travers le matériau échantillon. L'invention permet de créer de nouveaux matériaux de protection contre les rayonnements grâce à une détermination plus exacte de la part du poids de la charge selon les paramètres prédéterminés de masse et de poids.
