Natural radioactivity in aerosols collected in a NORM industry: radiological implications. Radioprotection, 44 (5), 377-382.1769-700Xhttps://hdl.handle.net/11441/99915On the frame of a broad project devoted to the evaluation of the occupational and environmentalradiological impact of several NORM industries located at the South-West Spain, a study determiningthe U-series radionuclides levels in air particulate matter has been accomplished inside a phosphate rockprocessing plant dedicated to phosphoric acid production. U-series radionuclides concentrations in aerosolscollected inside this plant have been determined and compared with those obtained in aerosols collectedfrom a reference monitoring station not affected by NORM industries or other anthropogenic inputs.Additionally, based on the observed increments in the volumetric concentrations of the radionuclides fromthe U-series in the plant, the increase in the occupational doses due to inhalation for their workers has beenestimated. Even under conservative assumptions, the dose enhancements are clearly below 1 mSv/year, theannual limit for the public.application/pdf6 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1051/radiopro/2009507220284503
