В настоящей работе впервые приводятся данные по оценке радиологической опасности природных вод восточных районов Новосибирской области. Выявлено, что на территории исследования развиты пресные и ультрапресные воды с величиной общей минерализации от 127 до 1848 мг/дм3, преимущественно HCO3 Mg-Ca, HCO3 Na-Mg-Ca и SO4-HCO3 Na-Mg-Ca состава. Геохимическая обстановка как восстановительная, так и окислительная (Eh (–332)–(+313) мВ), pH 6,1–9,5, содержание растворенного кислорода 0,51–16,59 мг/дм3. установлено, что наибольший вклад в природную радиоактивность вносят изотопы калий-40 и члены ряда радия (уран-238 и его продукты распада: уран-234, радий-226, радон-222 и др.). установленная активность калия-40, урана-238, радия-226, радона-222 варьирует в диапазоне от 0 до 85,5, от 0 до 4,3, от 0 до 25,2, от 1 до 1161 Бк/дм3 соответственно. Активность тория-232 на большей части территории исследования не превышает кларковые значения, за исключением вод, приуроченных к западной и северо-западной части Новосибирского гранитоидного массива (пгт. Колывань, с. скала и сопредельные территории).

Для оценки радиологической опасности природных вод, с использованием активности калия-40, радия-226 и тория-232, были рассчитаны: радиевый эквивалент (Raeq), мощность поглощенной из воздуха дозы (гамма-излучения) (Dγ), годовая эффективная эквивалентная доза (AEDE), индекс опасности внешнего и внутреннего облучения (Hex и Hint), пожизненный риск онкологического заболевания (ELCR). установлено, что природные воды восточных районов Новосибирской области в целом характеризуются низкими значениями всех радиологических параметров относительно норм, принятых международными организациями, находятся на одном уровне с природными водами Ирака, Намибии, Йемена, Испании, Китая и др. регионов мира и могут быть отнесены к категории безопасных вод для технического использования населением. В то же время использование природных вод для целей питьевого водоснабжения имеет существенные ограничения из-за повышенных и высоких концентраций радона-222, установленных как в зонах распространения гранитных массивов, так и в зонах распространения осадочных отложений.

Природа радиоактивности природных вод восточных районов Новосибирской области и уровень радиологического загрязнения окружающей среды контролируются геологическим строением, за исключением озерных вод около с. Шилово и около завода по производству кирпича в Дзержинском районе г. Новосибирска, где повышенная активность калия-40, вероятно, связана с использованием калийных удобрений в сельском хозяйстве и с использованием карбоната калия в процессе производства кирпича.

This paper presents an assessment of the radiological hazard associated with natural waters in the eastern part of Novosibirsk Oblast. The study area is characterized by fresh and ultra-fresh groundwater with total dissolved solids ranging from 127 to 1,848 mg/dm³, predominantly of HCO3 Mg-Ca, HCO3 Na-Mg-Ca and SO4HCO3 Na-Mg-Ca composition. The geochemical conditions vary from reducing to oxidizing (Eh from –332 to +313 mV), with pH values between 6.1 and 9.5 and dissolved oxygen concentrations ranging from 0.51 to 16.59 mg/dm³.

The primary contributors to natural radioactivity in these waters are 40K and members of the 238U decay series, including 234U, 226Ra, 222Rn, and other decay products. Measured activities were as follows: 40K – 0 to 85.5 Bq/dm3; 238U – 0 to 4.3 Bq/dm3; 226Ra – 0 to 25.2 Bq/dm3; and 222Rn – 1 to 1,161 Bq/dm3. Activity levels of thorium-232 generally clarke values, except in waters associated with the western and northwestern parts of the Novosibirsk granitoid massif (Kolyvan, Skala and adjacent areas).

To evaluate the radiological risk, several parameters were calculated based on the activities of 40K, 226Ra, and 232Th: radium equivalent activity (Raeq), absorbed gamma dose rate in air (Dγ), annual effective dose equivalent (AEDE), external and internal hazard indices (Hex and Hint), and excess lifetime cancer risk (ELCR). The results indicate that natural waters of the the eastern part of Novosibirsk Oblast generally exhibit low radiological parameter values – well within international safety standards – and are comparable to those reported for natural waters in Iraq, Namibia, Yemen, Spain, China, and other regions. Consequently, these waters can be classified as safe for domestic (non-potable) use.

However, their use for drinking water supply is significantly restricted due to elevated and high concentrations of 222Rn, observed both in areas underlain by granitic bedrock and in regions with sedimentary deposits.

The natural radioactivity of waters in the the eastern part of Novosibirsk Oblast and the overall radiological background of the environment are primarily controlled by local geological settings. Exceptions include lake waters near Shilovo village and near a brick-manufacturing plant in the Dzerzhinsky District of Novosibirsk, where elevated 40K activity is likely attributable to agricultural application of potassium fertilizers and the use of potassium carbonate in brick production, respectively.
