Abstract
Tadqiqotda Sirdaryo viloyatining uch tuproq-agroekologik tayanch nuqtasida 2021, 2022 va 2025-yillarda aniqlangan ¹³⁷Cs hamda ⁹⁰Sr faollik konsentratsiyalari qayta tahlil qilindi. 0-30 sm qatlam namunalari beta- va gamma-spektrometriya usullarida baholangan. Yillik qatorlarning arifmetik qayta hisobi ¹³⁷Cs uchun 4,47 Bq/kg, ⁹⁰Sr uchun 1,22 Bq/kg umumiy o‘rtachani berdi. 2021-2025-yillarda uch hudud bo‘yicha o‘rtacha ¹³⁷Cs 29,3%, ⁹⁰Sr 17,5% ga oshdi; ⁹⁰Sr 2022-yilda oraliq maksimum ko‘rsatdi. Maksimal qiymatlar ishchi nazorat chegaralarining 3,44% va 3,00% ini tashkil etdi. Shaffof qayta hisob o‘tloqi tuproqni nisbatan yuqori monitoring ustuvorligiga ega zona sifatida ajratdi.References
