Introduction. The important factors affecting health and performance of young people are the conditions of education, in particular, a comfortable microclimate in the classrooms of higher educational institutions. Materials and methods. In view of the urgency of this problem, an analysis was made of the microclimate parameters of educational organizations of different profiles (Ufa city, the Republic of Bashkortostan). 294 classrooms were studied in 22 buildings of 4 leading universities in Ufa. A total of 3,822 measurements were taken to determine the parameters of the microclimate. The analysis of ionizing radiation in the aerial environment of classrooms. There was performed determination of radon and its affiliated products content. In order to assess the conditions and lifestyle of students of 4 higher educational institutions of the city of Ufa, we conducted an anonymous survey of 1,820 students of I and IV years of education. Results. The average temperature in the classrooms of all universities studied was 23.9±0.09 C. The average relative humidity in all classrooms was 34.2 ± 0.42%. Analysis of ionizing radiation (radon and its daughter products decay) in the aerial environment of the classrooms and sports halls located in the basement determined that the average annual equivalent equilibrium volumetric activity of the radon daughter products (EROA ± Δ222Rn) ranged from 28 ± 14 to 69 ± 34.5 meter, which meets the requirements established by SanPiN. Conclusion. The hygienic assessment of the microclimate parameters of educational institutions of various profile revealed a number of deviations from the regulated norms. The results indicate the need to control the parameters of the microclimate, both from the administration of universities, and from the professors. According to the results of the study, recommendations were prepared for the management of higher educational institutions in Ufa.

<span lang="EN-US">Currently, telecommunications systems have become more widespread and there is still a discrepancy between whether or not non-ionizing radiation produces health problems in living beings at cellular level. From an experimental point of view, it is interesting to raise the correlation of high levels of electromagnetic pollution with health problems in urban populations which would make it possible to clearly determine the effects of this type of radiation on human health and the environment. By means of remote sensing, a geographic information system (GIS) has been developed for the analysis of electromagnetic pollution levels generated by emissions from non-ionizing radiation (NIR) sources in a city. A method for measuring electromagnetic pollution was applied, which allows the generation of a table of attributes of the GIS that is the input to generate by inverse distance weighting (IDW), the layer of electromagnetic pollution. The method, as a case study, was applied in the city of Manizales, located in Colombia, obtaining as a result a layer that allows evidence that the highest levels of electromagnetic pollution are concentrated in the most central area of the city. In this way, the effects of NIR on public health can be analyzed by means of correlations.</span>

The article presents results of study of delayed effects of occupational exposure to alpha and gamma radiation on human genome. The group of 23 former Mayak employees at the city of Ozersk was involved in the study. During their work at the enterprise for plutonium processing they had been exposed to internal and external radiation. Average internal alpha radiation dose to lungs was 0.120.024 Gy, to the bone marrow – 0.0450.0087 Gy. Average individualized ex-ternal gamma radiation doses to the bone marrow and to the lungs were 1.60.1Gy, 1.80.12 Gy, respectively. Impacts of ionizing radiation and alpha particles on frequency of micronuclear cells and the components of adaptive response were assessed. Adaptive potential of lymphocytes cor-relates with doses in internal and external radiation. Results of the analysis indicate that sponta-neous DNA damage to the lymphocytes genome is related to the level of internal rather than ex-ternal damage to irradiation, of human lungs (r=0.51; p=0.015) and the bone marrow (r=0.47; p=0.026), it depends also on the duration of wok with alpha and gamma emitters (r=0.43; p=0.046). Results of the study may be useful for estimating risk of delayed effects on health sta-tus of workers dealing with radionuclides processing.

Research relevance: article presents the incidence of children and grandchildren for 2018–2019 of liquidator workers who took part in cleaning up the contaminated area around the Chernobyl nuclear power plant, as well as residents evacuated from the city of Pripyat and other settlements within a radius of 70 km from the station. The consequences of radiation exposure of Chernobyl accident remain a topical issue. Research objectives: in order to study health status of children and grandchildren of liquidators, outpatient cards and reporting forms no. 15-zdrav “On medical care for people affected by radiation and included in the Kyrgyz State Medical and Dosimetric Register” examined. Research materials and methods: diseases of the endocrine and nervous systems, nutritional disorders, metabolic disorders, mental disorders, diseases of the eye and its adnexa, ear diseases of and mastoid process were studied. Circulatory and respiratory system diseases were analyzed. Research results: animal and cell culture studies show that high doses of ionizing radiation can lead to mutations in offspring. However, there have not been sufficiently large-scale studies on humans that would allow assessing the effect of radiation on the health of offspring. The exposure provokes mutations and incurable diseases, but it is still unclear how it might affect the children affected. It is known that exposure to ionizing radiation increases DNA mutagenesis compared to background values. Conclusions: obtained data substantiate the need for further monitoring of their health, organization of differentiated dispensary observation of this contingent and timely implementation of medical, rehabilitation and preventive measures in order to preserve health of “children and grandchildren of Chernobyl” at all subsequent stages of their life.

Objectives: The objective of this study was to evaluate the knowledge of professionals working in the radiology area of a public hospital in the city of Portoviejo, province of Manabí, Ecuador, on the application of ionizing radiation in diagnostic studies and their involvement in the use of protective measures. Methods: A questionnaire with closed questions was applied on the protection measures adopted by practitioners and the radiation doses they apply to patients, among others, to all occupationally exposed workers of the radiology service of the mentioned hospital. Results: The professionals surveyed show a moderate knowledge about the application of ionizing radiation, regardless of their years of experience and profession. Due to the type of radiological application, professionals only use shielding as a protection measure, but not personal dosimeters during operation with X-ray equipment. Conclusions: Professionals have received similar and adequate training; however, radiation update courses are required, particularly concerning radiation protection.

Modern surface analysis is based largely upon the use of ionizing radiation to probe the electronic and atomic structure of the surfaces physical and chemical makeup. In many of these studies the ionizing radiation used as the primary probe is found to induce changes in the structure and makeup of the surface, especially when electrons are employed. A number of techniques employ the phenomenon of radiation induced desorption as a means of probing the nature of the surface bond. These include Electron- and Photon-Stimulated Desorption (ESD and PSD) which measure desorbed ionic and neutral species as they leave the surface after the surface has been excited by some incident ionizing particle. There has recently been a great deal of activity in determining the relationship between the nature of chemical bonding and its susceptibility to radiation damage.

The Court of Appeals of New York held, in Council of the City of New York u. Giuliani, slip op. 02634, 1999 WL 179257 (N.Y. Mar. 30, 1999), that New York City may not privatize a public city hospital without state statutory authorization. The court found invalid a sublease of a municipal hospital operated by a public benefit corporation to a private, for-profit entity. The court reasoned that the controlling statute prescribed the operation of a municipal hospital as a government function that must be fulfilled by the public benefit corporation as long as it exists, and nothing short of legislative action could put an end to the corporation's existence.In 1969, the New York State legislature enacted the Health and Hospitals Corporation Act (HHCA), establishing the New York City Health and Hospitals Corporation (HHC) as an attempt to improve the New York City public health system. Thirty years later, on a renewed perception that the public health system was once again lacking, the city administration approved a sublease of Coney Island Hospital from HHC to PHS New York, Inc. (PHS), a private, for-profit entity.
