| description | The main goal of the presented research was the preliminary investigation of
possibility of red mud - Hungarian dump sites Almasfuzito (sample A) and Ajka
(sample B) - application as a pigment or as a raw material for use in the
construction materials industry. Also, the aim of this work was the
characterization of red mud as industrial waste generated by the Bayer
process in the aluminum industry - which may cause environmental problems if
appropriate treatment is not carried out. The main mineral phases of both red
mud are hematite (Fe2O3), calcite (CaCO3), gibbsite (Al(OH)3) and they
consists of particles of median particle size 2.1 mm (sample A) and 2.5 mm
(sample B) and have a characteristic red color, which was the reason for its
testing for use in the industry of building materials as a pigment for
standard concrete mixtures. The radionuclides content in the samples was
determined by gamma spectrometry, and the radiological hazards originating
from 238U, 232Th, 40K in the samples, were assessed through the radium
equivalent activity, and the external radiation hazard index. The absorbed
dose rate and the annual effective dose were calculated in accordance with
the UNSCEAR 2010 report and the results are presented in this paper. [Project
