Ushbu maqolada tabiiv suvlar radioaktivliligini oldindan baholash tadqiqotlari va ichimlik suvlarining izotopli tahlillarim o'tkazish natijalari keltirdgan. Suv n a ’munalarida 234U/238U izotoplari orasidagi radioaktiv muvozanatning buzilishi bo'yicha natijalar keltirdgan. Olingan natijalardan shu ma’lumki, yer osti suvlarida 234IJ izotopi konsentratsiyasi yer usti suvlaridagiga qaraganda vuqori.
Tayanch iboralar: ichimlik suvi, izotopli tahlil, radiokimyoviy tavvorgarlik, uran izotoplarini konsentratlash, ekstraksion bo'linma, hisob na’muna, radiatsion muvozanatning buzilishi, izotop konsentrasivasi, uzoq yashovchi alfa nurlanuvchi radionuklidlar.
Results o f a research ofpreliminary estimate o f radioactivity o f natural waters and carrying out the isotope analysis o f drinking waters are given in this article. Results on violations o f radioactive balance between isotopes - 234U/238U in water tests are given. From the received results it is visible that, in underground waters concentration o f isotope 234IJ is more than in surface water.
Key words: drinking-water, isotope analysis, radiochemical preparation, concentration o f uranium isotopes, extractor department, load, breach o f radioactive equilibrium, isotope concentration, long-lived alpha-emitting radionuclides.
