This study focuses on the radiological characterization of building materials manufactured in Albania by using a high-resolution gamma-ray spectrometer. The average activity concentrations of 40K, 226Ra and 232Th were, respectively, 644.1 ±64.2 Bq/kg, 33.4 ±6.4 Bq/kg and 42.2 ±7.6 Bq/kg in clay bricks and 179.7 ±48.9 Bq/kg, 55.0 ±5.8 Bq/kg and 17.0 ±3.3 Bq/kg in the cements. The calculated Activity Concentration Index (ACI), varied from 0.48 ± 0.02 to 0.63 ± 0.04 in the clay bricks and from 0.29 ± 0.03 to 0.37 ± 0.02 in the cements. Based on the ACI, all of the clay bricks and cements were categorized as A1 materials. We can exclude (at 3σ level) any restriction of their utilization as bulk materials.

Abstract

This study focuses on the radiological characterization of building materials manufactured in Albania by using a high-resolution gamma-ray spectrometer. The average activity concentrations of 40K, 226Ra and 232Th were, respectively, 644.1 ±64.2 Bq/kg, 33.4 ±6.4 Bq/kg and 42.2 ±7.6 Bq/kg in clay bricks and 179.7 ±48.9 Bq/kg, 55.0 ±5.8 Bq/kg and 17.0 ±3.3 Bq/kg in the cements. The calculated Activity Concentration Index (ACI), varied from 0.48 ± 0.02 to 0.63 ± 0.04 in the clay bricks and from 0.29 ± 0.03 to 0.37 ± 0.02 in the cements. Based on the ACI, all of the clay bricks and cements were categorized as A1 materials. We can exclude (at 3σ level) any restriction of their utilization as bulk materials.
