Title (EN) RADIATION SHIELDING SHEET
(FR) COUVERTURE DE PROTECTION CONTRE LES RAYONNEMENTS
(JA) 放射線遮蔽シート
Abstract: front page image
(EN)Disclosed is a radiation shielding sheet (1) obtained by filling an organic polymer material (2) with a shielding material (3). This radiation shielding sheet (1) is characterized in that the shielding material (3) is an oxide powder of at least one element selected from lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), samarium (Sm), europium (Eu) and gadolinium (Gd) which has an average particle diameter of 1-20 μm, and the filling factor of the shielding material (3) is 40-80% by volume.
(FR)L’invention concerne une couverture de protection contre les rayonnements (1) que l’on obtient en remplissant une matière polymère organique(2) avec un matériau de protection (3). Cette couverture de protection contre les rayonnements (1) est caractérisée en ce que le matériau de protection (3) est une poudre d’azote constituée par au moins un élément choisi parmi le lanthane (La), le cérium (Ce), le praséodyme (Pr), le néodyme (Nd), le samarium (Sm), l’europium (Eu) et le gadolinium (Gd) qui a un diamètre de particule moyen allant de 1 à 20 µm, et le coefficient de remplissage du matériau de protection (3) est de 40 à 80 % en volume.
(JA) 有機高分子材料2に遮蔽材料3を充填した放射線遮蔽シート1において、上記遮蔽材料3がランタン(La)、セリウム(Ce)、プラセオジム(Pr)、ネオジム(Nd)、サマリウム(Sm)、ユーロピウム(Eu)、ガドリニウム(Gd)から選択される少なくとも1種の元素の酸化物粉末であり、この酸化物粉末の平均粒径が1~20μmであり、かつ遮蔽材料3の充填率が40~80体積%であることを特徴とする放射線遮蔽シート1である。
