The aim of this work was to determine the contamination of I-131 in milk samples by low background γ-spectrometry and low background β-counting techniques in the vicinity of the Nuclear Center in Salazar, Mexico. The low background γ-spectrometry was done directly. The determination by low background β-counting consisted of a radiochemical separation of I-131 by ion exchange from the milk samples followed by measurement in a low background β-counting system. The results indicated that there was no contamination of I-131 in the samples.
