摘要

~(238)U, ~(234)U and ~(235)U were determined in tap water from municipal water pipes that drew their supply from surface water or ground water in various locations in Poland. Average activity concentrations of ~(238)U, ~(234)U and ~(235)U in tap water from surface water were 9.6±7.1, 12.8±9.7 and 0.41±0.31 Bq m~(-3), respectively, whereas from ground water they were 4.5±6.0, 5.7±6.9 and 0.19±0.27 Bq m~(-3), respectively. Activity concentrations of ~(234)U were higher than ~(238)U. Ratios of ~(234)U/~(238)U ranged from 1.07 to 2.60, indicating the lack of equilibrium between these isotopes. The average ~(235)U/~(238)U ratio was 0.043±0.008, being close to 0.046 for natural uranium. Average annual intake with water and food was 7.6±5.1 Bq for ~(238)U and 9.5±6.6 Bq for ~(234)U. Annual committed effective doses calculated from these intakes for adults were 0.34±0.23 and 0.47±0.32 μSv, respectively; ~(235)U contributed to the total dose from the uranium isotopes by about 2%.
