“…Aluminum, which is found in the form of different minerals in nature, is a soft and light metal that is the most widely used after iron in the industry and has a wide area of use due to its high electrical and thermal conductivity, low density, ability to turn into thin plates, and resistance to corrosion . Especially because of its light weight, aluminum has a wide range of use in the transportation and construction sectors, which require high-strength properties. − Bauxite, which is the main ore used in the production of aluminum metal, has become an indispensable raw material for many sectors. The corrosion of iron used as a building material seems to increase the use of aluminum day by day.…”

In this study, which consists of two parts, the radiological and chemical content of bauxite ore was investigated. Gamma-ray spectrometry was used in the first part of the study to determine the activity concentrations of natural radionuclides in samples taken from bauxite deposits in Turkey. The measured activity concentrations of 226Ra, 232Th, and 40K varied from 12.1 ± 2.5 to 132.6 ± 11.4 Bq kg–1 with a mean of 78.4 ± 8.3 Bq kg–1, 6.5 ± 0.5 to 97.3 ± 9.9 Bq kg–1 with a mean of 64.5 ± 5.9 Bq kg–1, and 5.1 ± 0.0 to 356.4 ± 40.1 Bq kg–1 with a mean of 52.6 ± 5 Bq kg–1, respectively. The calculated mean radium equivalent activity value is 177.4 Bq kg–1, the mean gamma dose rate absorbed in the air is 78.8 nGy h–1, the mean corresponding annual effective dose value is 96.6 μSv y–1, and the mean lifetime risk of cancer is 3.85 × 10–4. The chemical content of the bauxite samples was determined in the second part of the study using X-ray fluorescence spectrometry (XRF). For which sectors in the industry the existing bauxite deposits in Turkey can be used was investigated based on this information.
