COMPOSITION OF POLYMERIC TISSUE-EQUIVALENT SCINTILLATING DETECTOR OF GAMMA RADIATION Russian patent published in 1994 - IPC

FIELD: dosimetry of ionizing radiation. SUBSTANCE: effective atomic number of claimed composition is increased by tin salts of organic acids, general formula I (R₁COO)_lSn(R₂)_m . l = 1, m = 3, R₁ and R₂ = CnH_2n+1, where n = 1-17, l = m = 2 R₁ and R₂ = Ph, C_nH_2n+1, where n = 1-17 and radioluminophore is constituted by thiophene derivatives, general formula II , where R₁=R₂=R₃ at n = 0-4, polymer matrix consists of copolymer of methylmetacrylate with styrene and butylacrylate. Additionally, light output of composition is increased by naphthalene derivatives of general formula III R₁=C_nH_2n+1 where: a) = H, b) R₁=CH₃ R₂=R₃ = H, c) R₁ = H, R₂=R₃=CH₃ at the following ratio of components, wt. -% : agent increasing effective atomic number of composition, 2.5-3.0; radioluminophore, 1.2-2.0; agent increasing light output, 5.0-15.0; polymeric matrix, the balance. EFFECT: higher efficiency.
