The article discusses the problem of creating environmentally safe and radiation-resistant hybrid materials based on natural polymers for use in conditions of ionising radiation. The relevance of the research is substantiated by the shortcomings of traditional shielding materials. It considers their toxicity, complexity of disposal and limited effectiveness against various types of radiation.The aim of the article is to develop a conceptual scheme and algorithm for the creation of environmentally safe, radiation- resistant hybrid materials based on natural polymers for use in radiation technologies for various purposes.Methodology. The methodological basis of the study is a phased comprehensive approach, which includes: selection of natural polymers with high radiation resistance potential (in particular lignin); their chemical modification to improve interphase interaction with inorganic components; introduction of metal oxide nanofillers with radiation-protective properties; synthesis of hybrid materials under controlled technological conditions. It is proposed to use a set of analytical methods to characterize the structure, morphology, thermal stability and functional properties of materials: FTIR spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and mechanical testing before and after exposure to ionising radiation.Scientific novelty. For the first time, an algorithm for creating hybrid materials based on natural polymers was proposed, taking into account environmental safety, biocompatibility and the ability to neutralize the harmful side effects of radiation exposure (secondary electrons, radicals).Conclusion. The article substantiates the feasibility of creating environmentally safe and radiation-resistant hybrid materials based on natural polymers as an alternative to traditional shielding agents. A conceptual scheme and algorithm for the synthesis of such materials was developed, covering the selection of the base biopolymer, its modification, the integration of inorganic nanocomponents, and further testing of the finished composite. The effectiveness of using lignin is justified due to its radiation resistance and antioxidant properties. Approaches to the introduction of metal oxides for the neutralization of secondary electrons and radicals were proposed, providing multi-level protection against ionizing radiation.
