Описаны результаты анализа содержания урана в антропогенных карбонатах (накипи) на территории Уфы по данным изучения 42 проб. Медианное содержание урана в изученных образцах составляет 1,44 мг/кг, что существенно ниже фоновых показателей (накипь из воды оз. Байкал, кларк осадочных карбонатных пород) и данных по другим населенным пунктам Республики Башкортостан. Пониженные значения урана вероятно связаны с влиянием трех ведущих факторов: особенностей геологического строения территории (гипсы, известняки); типов водоснабжения; процессов водоподготовки при централизованном типе водоснабжения. Для пространственного распределения урана в антропогенных карбонатах характерен однородный тип, который нарушается в двух случаях: смена типа водоснабжения (централизованное на индивидуальное); материал посуды, в которой кипятится вода. При сравнительном анализе проб антропогенных карбонатов, связанных с различными источниками водоснабжения (ковшовый и инфильтрационный водозаборы) и типами домашних фильтров, значимых различий не выявлено.

The paper presents the results of analyzing uranium content in man-made carbonates (scale crusts) on the territory of Ufa based on examination of 42 samples. The median uranium content in the investigated samples stands at 1.44 mg/kg, which is significantly lower than the background values (scales from the Lake Baikal water, a clarke of sedimentary carbonate rocks) and data on other settlements of the Republic of Bashkortostan. Low values of uranium content are probably associated with the effects of the three leading factors, i.e. specific subsurface geology of the territory (gypsum, limestone); types of water supply; water treatment processes for the centralized type of water supply. Spatial distribution of uranium in man-made carbonates is characterized with uniformity, which is disturbed in two cases, i.e. a change of the water supply type (from centralized to individual); and material of the vessels used for boiling the water. No significant differences were detected when comparing samples of man-made carbonates associated with different sources of water supply (the bucket and infiltration types of water intake) and the types of household filters.
