Abstract
This study aims to evaluate the radiation doses from building materials, including sand, cement, brick, faience, plaster and marble, collected from different sites in eastern Algeria. The specific activities of natural radionuclides, mainly represented by the natural radioactive series 238U, 232Th and primordial 40K, were determined using a gamma spectrometry system equipped with a high purity germanium (HPGe) detector. Radiological hazard parameters (Raeq, Hex, Hin, Iγ and Iα) associated with these activities were calculated to determine the suitability of the construction materials. To assess their radiological risks to human health, an analysis of absorbed dose rate (D), annual effective dose (AED) and excess lifetime cancer risk (ELCR) was performed and the results examined and compared with those reported elsewhere. The findings obtained for these samples are within the limits of internationally recommended values.
期刊介绍：
Isotopes in Environmental and Health Studies provides a unique platform for stable isotope studies in geological and life sciences, with emphasis on ecology. The international journal publishes original research papers, review articles, short communications, and book reviews relating to the following topics:
-variations in natural isotope abundance (isotope ecology, isotope biochemistry, isotope hydrology, isotope geology)
-stable isotope tracer techniques to follow the fate of certain substances in soil, water, plants, animals and in the human body
-isotope effects and tracer theory linked with mathematical modelling
-isotope measurement methods and equipment with respect to environmental and health research
-diagnostic stable isotope application in medicine and in health studies
-environmental sources of ionizing radiation and its effects on all living matter
