The use of ionizing radiation processing technologies has proven to be one of the most versatile ways to prepare a wide range of membranes with specific tailored functionalities, thus enabling them to be used in a variety of industrial, environmental, and biological applications. The general principle of this clean and environmental friendly technique is the use of various types of commercially available high-energy radiation sources, like 60Co, X-ray, and electron beam to initiate energy-controlled processes of free-radical polymerization or copolymerization, leading to the production of functionalized, flexible, structured membranes or to the incorporation of functional groups within a matrix composed by a low-cost polymer film. The present manuscript describes the state of the art of using ionizing radiation for the preparation and functionalization of polymer-based membranes for biomedical and environmental applications.

Abstract Radiation sterilization has been considered a mass decontamination technique for biodegradable cultural heritage (CH) since its widespread application in the medical field. Initial experiments have revealed advantages, for example, efficiency and effectiveness, but also disadvantages, namely “side effects” concerning CH materials. More than 50 years later, the adequacy of ionizing radiation for some CH artefacts is still the subject of discussion. The main reason why is that science and industry are not yet able to provide a more efficient technique for treating mass decontamination. For wooden items, there is general agreement that the irradiation dose required for insect eradication is not damaging, even in the case of polychromed wood. For cellulose pulp (paper), there is a reduction in polymerization degree (DP) at the high doses necessary to stop the attack of fungi, but this should be considered taking into account the purpose of the treatment. Emergency or rescue treatments are necessary to mitigate the consequences of accidents or improper storage conditions. In some cases (archives), the value of written information is greater than the historical value of the paper support. For other materials, namely textiles, leather and parchment, less research has been published on the effect of ionizing radiation treatment. As a general rule, irradiation is not necessary when only a few CH elements are present that are affected by biological contamination since restorers can solve the problem by classical means. The need for radiation treatment arises when large collections (hundreds, thousands or even more elements) are heavily affected by the biological attack. In Romania, the IRASM gamma irradiator of IFIN-HH is receiving an increasing number of requests for CH treatment, mainly due to an intensive research programme concerning this topic and close liaison with CH owners or administrators. Besides reviewing the scientific results obtained in Romania and abroad, this paper presents some examples from experiences in Romania.

Due to the special importance of food in the emergence of acute intestinal infectious diseases and bacterial food poisoning, special attention is paid to the microbiological purity monitoring of food raw materials and food products. Ionizing radiation processing of food – is a promising technology for combating both microorganisms causing spoilage and pathogenic and opportunistic microorganisms – pathogens of dangerous diseases. However, work with vegetative forms of these microorganisms to study the effects of ionizing radiation is difficult because of the need to use in experiments only actively growing culture, which is sensitive to various environmental factors. When studying the effect of ionizing radiation on the microflora of food products, this study describes the investigation of the possibility of using as a test-culture the ascospores of the fungus Aspergillus fischeri instead of vegetative forms of pathogenic and opportunistic cultures. Ascospores of the fungus Aspergillus fischeri are used as a test culture in the development of pasteurization regimes of fruit and vegetable products. A. fischeri ascospores have been shown to have higher resistance to ionizing radiation in the range from 1 to 5 kGy at capacity 10 MeV in comparison with Salmonella enterica, Escherichia coli and Listeria monocytogenes cells. Therefore, in the development of ionizing radiation food processing regimes it is recommended to use ascospores of the fungus A. fischeri as a test culture instead of vegetative forms of bacteria.
