Purpose of the work: to reveal the regularities of interaction of photon radiation with polydisperse systems for search of new approaches to creation of radioprotective and x-ray contrast materials. Methods of the research and equipment: dosimetry, sedimentation, photometry, x-ray, microscopy, electron microscopy. Results and their novelty: polydisperse systems more considerably attenuate x-rays, especially low-energy, when compared with monodisperse. Addition of A5 improves physico-chemical, x-ray properties and reduces gastrointestinal toxicity of water suspensions of polydisperse x-ray contrast medium BaSo4. Area of application: medicine, radiology, radiation medicine. Product Description popup.authors popup.nrat_date 2020-04-02 Close
