PROCÉDÉ DE FABRICATION DE FEUILLE DE PROTECTION CONTRE LES RAYONNEMENTS DÉPOURVUE DE PLOMB, ET FEUILLE DE PROTECTION CONTRE LES RAYONNEMENTS DÉPOURVUE DE PLOMB
Disclosed is a method for manufacturing a lead-free radiation shielding sheet. The method for manufacturing a lead-free radiation shielding sheet according to the present invention comprises a coating film lamination step of repeating a process of sequentially: applying, to one side of a base material for forming a radiation shielding sheet, a radiation shielding material containing radiation shielding powder and a binder for forming a film that are mixed together; laminating same; drying same; and integrating same, so as to form a multi-layered radiation shielding coating film on the one side of the base substrate. According to the present invention, lead, which is heavy and harmful to the human body and the environment, is not used, and thus side effects such as diseases and environmental pollution caused by lead do not occur; it is possible to lighten the weight of the radiation shielding sheet and manufacture protective clothing having excellent wearability; and flexibility can be improved compared to that of a lead rubber sheet, and thus handling and storage are convenient. In addition, the lead-free radiation shielding sheet manufactured by the present invention can be applied to clothing having various designs and radiation protection means for various uses due to flexibility and ease of manipulation.L'invention concerne un procédé de fabrication d'une feuille de protection contre les rayonnements dépourvue de plomb. Le procédé de fabrication d'une feuille de protection contre les rayonnements dépourvue de plomb selon la présente invention comprend une étape de stratification de film de revêtement consistant à répéter successivement le processus suivant : l'application, sur un côté d'un matériau de base, pour former une feuille de protection contre les rayonnements, d'un matériau de protection contre les rayonnements contenant une poudre de protection contre les rayonnements et un liant qui sont mélangés ensemble pour former un film ; la stratification de cel
