Information × Registration Number 0212U004890, 0108U003120 , R & D reports Title Development of manufacturing techniques of dosimeters on the basis of polymeric and polycrystalline materials for registration of radionuclides in environmental objects. Making of pre-production models of dosimeters for the determination of low radioactivity of ? radionuclides in the water environment. popup.stage_title Head Belikov Kostyantyn Mykolajovich, Кандидат хімічних наук Registration Date 07-02-2012 Organization State Scientific Institution "Institute for Single Crystals", National Academy of Sciences of Ukraine popup.description2 It is studied the sorption properties of mordenite, synthetic hydroxylapatite and silica gel "Enterosgel". it is shown the mordenite, synthetic hydroxylapatite and silica gel "Enterosgel" to effective for removal of cesium and strontium from model solutions. it is studied the sorption process of cesium and strontium ions by polymer balls impregnated by calix[4]crown-6 ether and calix[6]areneamide correspondingly. it is shown the given material is the effective sorbent for removing strontium and cesium ions from solutions do not containing calcium ions. it is proposed the method for obtaining the sorption-scintillation system by means of pressing of mixture of sorbent, porous forming agent and highly dispersion p-terphenyl. on the basis of the detailed studies of the properties it is developed the technique for selective determination of 90Sr in the water samples.
