X-RAY ABSORBING MATERIAL Russian patent published in 2001 - IPC

FIELD: shielding of personnel and equipment against roentgen and gamma radiation. SUBSTANCE: used as filler for material whose matrices acquire working condition under abnormal conditions and for its alternative capable of suppressing secondary penetrating radiation due to tunneling effect of penetratingradiation photons is polydispersional mixture incorporating particles of one material or its chemical composition, or their compounds within volume of matrix that acquires working condition under abnormal conditions. Total mass of segregated polydispersional mixture of X-ray absorbing filler is chosen from equation M = (0.51-0.999)m, where M is total mass of segregated polydispersional mixture; m is mass of X-ray absorbing filler, designed to meet conditions of X-ray shielding properties for pure X-ray absorbing filler. Material matrix nay be chosen of composite structure incorporating homogeneous base matrix and intermediate medium. Matrix and intermediate-medium fillers incorporate similar mixtures or those differing in chemical composition. EFFECT: enlarged functional capabilities. 2 cl, 3 ex
