“…The Campania region (southern Italy) is characterized by a diversified geology mainly because of the volcanic origin of its soils and formations from different geological eras (Guarino et al, 2022). This results in a different distribution of the natural radioactivity content in the soils (Ambrosino et al, 2023).…”

Introduction: Risk assessment of exposure to indoor pollutants plays an increasingly important role in human protection, and one of the main sources of indoor pollutants is building materials (BMs). In addition, production processes, including those related to BMs, are also involved in economic transition: the use of by-products from other industrial sectors as raw materials for the production processes in compliance with environmental sustainability is evaluated.Methods: In this work, we evaluate not only the radiation protection of BMs but also the possibility of adopting the circular economy principles. The two main objectives of this study were 1) radiometric characterization and calculation of Index I of pozzolan from Altavilla Irpina (Avellino) in Italy, used as a natural igneous additive for concrete, using gamma spectroscopy, and 2) comparison of different methodologies for calculating the annual effective dose of BMs (CEN/TR 17113:2017, RESRAD-BUILD software, and a previously developed experimental method). The same approach was extended to the possibility of reusing fly ash—a naturally occurring radioactive material (NORM) by-product of coal combustion in thermal power plants—for the production of concrete.Results and Discussion: The study aligns with the principles linked to the circular economy to extend the life cycle of materials by reducing the need for natural resources, suggesting a possible positive compromise between radioprotection and preservation of environmental heritage.

The study of radionuclides is very important in our daily life as these impose health implications to the general public. In present study the estimation of radionuclides in Ganderbal and Budgam districts of Kashmir Province using NaI(Tl) gamma-ray spectro-meter has been carried out. Radium, thorium, and potassium activity concentrations have been observed to range from 25±3 to 33±5 Bqkg−1, 3±2 to 11±3 Bqkg−1 and 415±63 to 601±80 Bqkg−1with average values of 29 Bqkg−1, 5 Bqkg−1 and 514 Bqkg−1, respectively. The radium equivalent activity (Raeq) for the soil samples has been evaluated and was found in the range of 107 to128 Bqkg−1 with the mean value of 116 Bqkg−1. It has been inferred that the radium equivalent activity (Raeq) lies in the permissible limits of 370 Bqkg−1 set by United Nations Scientific Committee on the Effects of Atomic Radiation. Absorbed dose and annual effective dose (indoor and outdoor) values were found to vary from 34 to 43 nGyh−1, 0.17 to 0.21 mSv and 0.04 to 0.05 mSv, respectively. Also, hazard indices (external and internal) are calculated from the specific concentration of radium, thorium and potassium which are found less than unity as recommended by organization for economic cooperation and development (OECD). Therefore, it can be concluded that the present study area does not pose any health implication to the general public.
