    The article deals with the issues of normative and methodological support of radiation survey of buildings and structures to be demolished. It is noted that with the intensive growth of construction of dwellings and public buildings in large cities, former industrial territories with a significant number of facilities to be demolished are being included into the development zone. The radiation monitoring and sorting of industrial waste generated after the demolition of buildings is not feasible in practice. The expediency of radiation survey of buildings and structures to be demolished at the stage preceding their dismantling, as well as the need to develop and approve at the federal level the methodology of its implementation is substantiated. Recommendations for the assessment of radiation safety indicators of buildings and structures to be demolished are given. It is shown that if the value of ambient equivalent gamma dose rate in the buildings and structures to be demolished does not exceed 0.6 ΞΌSv/h, industrial waste generated after demolition of buildings and structures and containing only natural radionuclides are not a subject to any restrictions related to the radiation factor, since the value of effective activity concentration of natural radionuclides is guaranteed not to exceed 1500 Bq/kg and therefore the waste is classified as Category I in accordance with the Basic sanitary rules for the provision of radiation safety (OSPORB 99/2010).Π’ ΡΡ‚Π°Ρ‚ΡŒΠ΅ Ρ€Π°ΡΡΠΌΠ°Ρ‚Ρ€ΠΈΠ²Π°ΡŽΡ‚ΡΡ вопросы Π½ΠΎΡ€ΠΌΠ°Ρ‚ΠΈΠ²Π½ΠΎ-мСтодичСского обСспСчСния Ρ€Π°Π΄ΠΈΠ°Ρ†ΠΈΠΎΠ½Π½ΠΎΠ³ΠΎ контроля Π·Π΄Π°Π½ΠΈΠΉ ΠΈ сооруТСний, ΠΏΠΎΠ΄Π»Π΅ΠΆΠ°Ρ‰ΠΈΡ… сносу.

    The paper presents results of a comprehensive radiation survey conducted in 2019 in six districts of the eastern part of the Orenburg region in 37 settlements with previously found elevated levels of activity concentration of natural radionuclides in tap water from groundwater sources of drinking water supply. The survey included measurements of indoor radon concentrations and EEC in residential and public buildings, as well as measurements of ambient dose equivalent rate of gamma radiation indoors and outdoors. The survey revealed that annual average indoor radon EEC in many residential buildings in 23 settlements and public buildings in 25 settlements exceeded the hygienic norm (action level) of 200 Bq/m3 adopted in Russia for existing buildings. The highest values of annual average indoor radon EEC were obtained in residential buildings in Novovinnitskoe (1242 Bq/m3), Bratslavka (987 Bq/m3) and Anikhovka (942 Bq/m3) in Adamovsky district, and in public buildings in Kvarkeno (2291 Bq/m3) in Kvarkensky district, Karabutak (1114 Bq/m3) and Novovinnitskoe (923 Bq/m3) in Adamovsky district. The established hygienic norms in terms of ambient dose equivalent rate indoors and outdoors were not exceeded in the surveyed settlements. Results of the survey showed that the main reason for high indoor radon concentrations in residential and public buildings in the settlements of the eastern part of the Orenburg region is not related to the usage of tap water from groundwater sources of drinking water supply with elevated levels of activity concentration of natural radionuclides.Π’ ΡΡ‚Π°Ρ‚ΡŒΠ΅ ΠΏΡ€ΠΈΠ²Π΅Π΄Π΅Π½Ρ‹ Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ комплСксного Ρ€Π°Π΄ΠΈΠ°Ρ†ΠΈΠΎΠ½Π½ΠΎΠ³ΠΎ обслСдования, ΠΏΡ€ΠΎΠ²Π΅Π΄Π΅Π½Π½ΠΎΠ³ΠΎ Π² 2019 Π³.

    The relationship between Sjogren’s syndrome, systemic sclerosis and lymphoproliferative diseases

    Despite the large number of studies devoted to the study of systemic sclerosis (SSc), the high risk of developing lymphomas in this disease, the relationship of their development with certain subtypes of SSc and specific SSc-associated autoantibodies is still debated in the literature. Aim.To study demographic, clinical, laboratory and immunological characteristics of patients with a combination of primary Sjogrens syndrome (pSS) and SSc and diagnosed lymphoproliferative diseases (LPDs); to characterize morphological/immunomorphological variants and course of non-Hodgkins lymphomas (NHL), developing in patients with these rheumatic diseases (RDs). Materials and methods.In 19982018 at the Nasonova Research Institute of Rheumatology, 13 patients with clinical and laboratory manifestations of pSS (12) and SSc (13) were diagnosed with various lymphoproliferative diseases (LPDs). In 3 cases, an induced RD was observed: 1 case of a diffuse, rapidly progressive form of SSc, 2 cases of pSS in combination with a limited form of SSc after chemotherapy and radiation therapy of Hodgkins lymphoma (1), B-cell NHL (1) and CR of the breast (1) respectively. The first 2 cases were excluded from the analysis, since the development of lymphomas is not pathogenetically associated with RD. Results.Of 11 patients with LPDs, 10 after a long course of RDs were diagnosed with NHL [MALT lymphoma of the parotid salivary glands 7, disseminated MALT lymphoma 2, disseminated MALT lymphoma with transformation into diffuse large B-cell lymphoma (DLBCL) 1]. RDs debuted with Raynauds phenomenon (RP) in 64.5% and pSS manifestations in 45.5% of patients. Stomatological manifestations of pSS were characterized by recurrent parotitis in 36%, significant parotid gland enlargement with massive infiltration of labial salivary glands (focus score 4) in 100%, severe xerostomia in 70%, extraglandular manifestations and lymphadenopathy in 50% of patients. The course of the SSc was characterized by mild RP with various types of capillaroscopic changes and mild lung changes and non-significant progression during long-term follow-up (median 22 years). The entire spectrum of SSс specific antibodies (anticentromere antibodies 60%, antibodies to ribonucleoprotease III 30%, Pm/Scl 10%), excepting antibodies to topoisomerase I, as well as pSS specific autoantibodies (antiRo/La 70%, RF (rheumatoid factor) 90%), were detected in patients with a combination of these RDs. Conclusion.pSS is often combined with a limited form of SSc regardless of the type of autoantibodies detected. The presence of pSS, rather than SSc, is a high-risk factor for the development of NHL in this group of patients. The patients with pSS and SSc are characterized by a steady progression of pSS with a slow and mild course of SSc throughout the observation period. The development of severe stomatological manifestations and high immunological activity of pSS contribute to the development of localized MALT lymphomas (70%) and disseminated MALT lymphomas (30%) with primary lesions of the salivary glands and transformation into DLBCL in case of their late diagnosis. The optimal method for preventing the development of NHL in this group of patients is the early diagnosis of pSS, the appointment of alkylating cytotoxic agents and/or anti-B-cell therapy in the early stages of pSS. Given the possibility of transformation of localized NHL into DLBCL, for early diagnosis, minimally invasive surgical biopsies of significantly enlarged parotid salivary glands should be performed before glucocorticoids are prescribed. Detection of positive B-cell clonality and lymphoepithelial lesions in the parotid salivary gland is considered a predictor of MALT lymphoma development during follow-up. Localized and disseminated MALT lymphomas in patients with pSS and SSc respond well to therapy, in contrast to MALT lymphomas transformed into DLBCL

    The paper presents data on indoor radon concentrations in the buildings of children institutions in a number of regions of the Russian Federation. The results of detailed radon surveys in 132 buildings of children institutions in 85 settlements of six districts of the Leningrad Region conducted in 2018-2020 were analyzed. In 14 buildings of children institutions in the Leningrad region (10.5% of all surveyed buildings) the hygienic limit on the indoor radon EEC was exceeded, the maximum measured value of radon concentration in the premises of children institutions reached 2200 Bq/m3. It seems appropriate to extend the experience of cooperation between the Directorate of the Rospotrebnadzor for the Leningrad Region and the Saint-Petersburg Research Institute of Radiation Hygiene after Professor P.V. Ramzaev in conducting detailed radon surveys in children institutions on other regions of the Russian Federation that face problems with indoor radon.Π’ ΡΡ‚Π°Ρ‚ΡŒΠ΅ ΠΏΡ€ΠΈΠ²Π΅Π΄Π΅Π½Ρ‹ Π΄Π°Π½Π½Ρ‹Π΅ ΠΎ содСрТании Ρ€Π°Π΄ΠΎΠ½Π° Π² Π²ΠΎΠ·Π΄ΡƒΡ…Π΅ ΠΏΠΎΠΌΠ΅Ρ‰Π΅Π½ΠΈΠΉ Π² зданиях дСтских ΡƒΡ‡Ρ€Π΅ΠΆΠ΄Π΅Π½ΠΈΠΉ ряда ΡΡƒΠ±ΡŠΠ΅ΠΊΡ‚ΠΎΠ² Российской Π€Π΅Π΄Π΅Ρ€Π°Ρ†ΠΈΠΈ, ΠΏΡ€ΠΎΠ°Π½Π°Π»ΠΈΠ·ΠΈΡ€ΠΎΠ²Π°Π½Ρ‹ Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ Π΄Π΅Ρ‚Π°Π»ΡŒΠ½Ρ‹Ρ… радономСтричСских обслСдований 132 Π·Π΄Π°Π½ΠΈΠΉ дСтских ΡƒΡ‡Ρ€Π΅ΠΆΠ΄Π΅Π½ΠΈΠΉ Π² 85 насСлСнных ΠΏΡƒΠ½ΠΊΡ‚Π°Ρ… 6 Ρ€Π°ΠΉΠΎΠ½ΠΎΠ² ЛСнинградской области, ΠΏΡ€ΠΎΠ²Π΅Π΄Π΅Π½Π½Ρ‹Ρ… Π² 2018–2020 Π³Π³.
