Description

In the present paper we analyze radioactive emissions from the selfradiolytical processes in radioluminescent composite materials based on tritium labeled polymers. We studied tritium labelled siloxanic polymers obtained by hydrolysis of: ethyl-T2-SiCl3+SiCl4; ethyl-T2-SiCl3+phenyl-SiCl3+SiCl4; ethyl-T2-SiCl3+phenyl-SiCl3; ethyl-T2-phenyl-SiCl2+SiCl4; propyl-T2-SiCl3+SiCl4; propyl-T2-SiCl3+phenyl-SiCl3+SiCl4; propyl-T2-SiCl3+phenyl-SiCl3; propyl-T2-phenyl-SiCl2+SiCl4 and tritiated oligomers 1,4-diphenyl-butane-T8; 1,4-diphenyl-2-butene-T6; 1,4-diphenyl-butadiene-T4, oligomers poly-1,4-diphenyl-butadiene. Radioactive emissions analysis was carried out by storage activity loss determination in conditions similar to those of radioluminescent pigments. The results obtained were compared with the results obtained by ESR spectroscopy on inactive polymeric structures and by quantum mechanical simulation. (authors)
