With the increase in instrumental sensitivity, it is now possible to measure ultratrace levels of many radioisotopes.The aim of this work was to determined the natural radionuclides (<sup>232</sup>Th,<sup> 234</sup>U, <sup>235</sup>U and<sup> 238</sup>U) in surface water using Inductively Coupled Plasma-Sector Field Mass Spectrometry (ICP-SFMS). The samples were sampling from Lerma river, State of Mexico at february to april 2015. The process of treatment of sample consisted in perform an acid digestion according to the 3015A USEPA method followed of the direct measurement in ICP-SFMS. Results obtained were: a) identify the presence of <sup>232</sup>Th,<sup> 234</sup>U,<sup> 235</sup>U and <sup>238</sup>U isotopes in water, b) isotopic ratios were for <sup>234</sup>U/<sup>238</sup>U=1.133 ± 0.016. ICP-SFMS has gained popularity in the field of radiochemistry, particularly as a method of detection for long lived-actinides.</p> ER -
