EPIDEMIOLOGY OF MALIGNANT NEOPLASMS AMONG WOMEN LIVING IN THE ZONE OF INFLUENCE OF RADIOACTIVE WASTE STORAGE FACILITIES
Introduction. Kazakhstan holds 14% of the world's uranium reserves, accounting for almost 88% of world production in 2013. Previous studies indicate that indoor and outdoor gamma dose rates and radon concentrations in the area exceed acceptable limits. Current research is evaluating the impact of uranium radioactive waste storage facilities on cancer epidemiology in nearby areas.
Materials and methods. The study included critical and control zones. The critical zone included the cities of Aksu, Kvartsytka, Zavodskoy, Shantobe and Stepnogorsk, located less than 5 km south of the tailings of the Hydrometallurgical Plant, and in the control group - Akkolsky district, 90 km from the storage of radioactive waste. Data obtained from the Electronic Register of Cancer Patients of the Republic of Kazakhstan.
Results. A total of 2,271 cases of cancer were reported between 2001 and 2015. The prevalence of malignant neoplasms in the main group was 35.02 per 1000 population versus 26.4 per 1000 people in the control group (χ2 = 23.9, p = 0.00). The prevalence of oncological diseases among the female population living in the area of action of radioactive waste storage facilities was 17.55 per 1000 population and was also statistically significantly higher than this indicator in the control group - 12.88 (χ2 = 14.3, p = 0.00).
Conclusion. In general, the study indicates the negative impact of the tailings of the hydrometallurgical plant on the environment and the occurrence of cancer.
