This paper discusses the current problem of the electronic memory reliability in terms of the ionizing radiation effects. The topic is actual since the high degree of components' miniaturization integrated into the flash memory causes the extreme sensitivity of this memory type to the ionizing radiation effects. The effects of ionizing radiation may cause changes in stored data, or even the physical destruction of the components. At the end, the experimentally and numerically obtained effects of radiation on specific flash memories are shown and discussed. The results obtained by laboratory and numerical experiments showed good agreement with each other and with the theoretically expected results.

Irradiation Process

Ionizing radiation has been widely used in industrial processes, especially in the sterilization of medicals, pharmaceuticals, cosmetic products, and in food processing. Similar to other techniques of food processing, irradiation can induce certain alterations that can modify both the chemical composition and the nutritional value of foods. These changes depend on the food composition, the irradiation dose and factors such as temperature and presence or absence of oxygen in the irradiating environment. The sensitivity of vitamins to radiation is unpredictable and food vitamin losses during the irradiation are often substantial. The aim of this study was to discuss retention or loss of vitamins in several food products submitted to an irradiation process.

Background.Exposure to ionizing radiation could affect the brain and eyes leading to cognitive and vision impairment, behavior disorders and performance decrement during professional irradiation at medical radiology, including interventional radiological procedures, long-term space flights, and radiation accidents. Objective. The objective was to analyze the current experimental, epidemiological, and clinical data on the radiation cerebro-ophthalmic effects. Materials and methods. In our analytical review peer-reviewed publications via the bibliographic and scientometric bases PubMed / MEDLINE, Scopus, Web of Science, and selected papers from the library catalog of NRCRM – the leading institution in the field of studying the medical effects of ionizing radiation – were used. Results. The probable radiation-induced cerebro-ophthalmic effects in human adults comprise radiation cataracts, radiation glaucoma, radiation-induced optic neuropathy, retinopathies, angiopathies as well as specific neurocognitive deficit in the various neuropsychiatric pathology including cerebrovascular pathology and neurodegenerative diseases. Specific attention is paid to the likely stochastic nature of many of those effects. Those prenatally and in childhood exposed are a particular target group with a higher risk for possible radiation effects and neurodegenerative diseases. Conclusions. The experimental, clinical, epidemiological, anatomical and pathophysiological rationale for visual system and central nervous system (CNS) radiosensitivity is given. The necessity for further international studies with adequate dosimetric support and the follow-up medical and biophysical monitoring of high radiation risk cohorts is justified. The first part of the study currently being published presents the results of the study of the effects of irradiation in the participants of emergency works at the Chornobyl Nuclear Power Plant (ChNPP). Key words: ionizing radiation, cerebroophthalmic effects, neurocognitive deficit, radiation accident, radiation cataracts, macular degeneration.

This paper deals with the flash memory reliability in terms of the ionizing radiation effects. In fact, the reliability of flash memory depends on physico-chemical restrictions of electrostatic nature due to the effects of ionizing radiation. The presented results are actual as a high degree of integrated components miniaturization affects the memory sensitivity, while the role of memories in the solar cells management system for space flights is increasing, so that the effects of ionizing radiation may cause changes in the stored data or the physical destruction of the flash memory components.

The present study evaluated the effects of proton and gamma-ray ionizing radiation on the mouse eye. The aim of this work was to analyze radiation-mediated retinoid oxidation in the retina and retinal pigment epithelium (RPE). The findings from this analysis can be used to develop a noninvasive method for rapid assessment of the effects of ionizing radiation. Comparative fluorescence and chromatographic analyses of retinoids before and after irradiations were performed. The fluorescent properties of chloroform extracts from irradiated mouse retina and RPE exhibited an increase in fluorescence intensity in the short-wave region of the spectrum (λ < 550 nm). This change is due to increased retinal and RPE retinoid oxidation and degradation products after radiation exposure. Comparative analyses of radiation effects demonstrated that the effect of proton exposure on the retina and RPE was higher than that of gamma-ray exposure. The present study revealed a new approach to assessing the level of radiation exposure in ocular tissues.
