Assessment of internal dose caused by uranium isotopes for workers in the phosphatic industry using alpha spectrometry

There is probability of exposure to uranium for workers in the phosphate industry (Internal exposure) by inhalation, and the deposition of this uranium in organs and tissues, and the consequence excretion out of the body by perspiration or urine. This study focuses on the determination of uranium in urine samples of workers. Some results seem to be higher than the detection limit of the method, therefore routine monitoring is required for those workers. (author)
