In this work, the radon emanation coefficients for selected building materials that are most often used in Serbia for covering floor surfaces (concrete, concrete screed, granite, glazed ceramic tiles, marble, roofing tile, and terrazzo tile) were determined, and the influence of the material structure on their values. The concentration of 226Ra activity in the samples was determined using the gamma spectrometry method. Radon emanation was measured with the RAD7 device. The porosity of the samples was tested using mercury intrusion porosimetry and water absorption methods, and the structural analysis was performed using X-ray diffraction analysis and X-ray fluorescence analysis. The measured values of 226Ra activity concentrations were in the range (4.93 – 298) Bq kg-1, and the estimated values of the radon emanation coefficients were in the range (0.55 – 6.05) %. The obtained results indicate that the chemical and mineralogical composition, method of production, and the 226Ra activity concentration have an influence on the emanation of radon from the material. No significant correlation was found between the radon emanation coefficient and the open porosity of the material, most likely due to the inhomogeneous presence of pores of different dimensions in the materials. It was established that the total value of the emanation coefficient depends on the emanation coefficient for pores ≤100 μm in size.

“…humans are constantly presented to natural radiation, which is mostly because of the activity of characteristic radionuclides 238U (226Ra), 232Th chains, the radioactive isotope 40K, and their radioactive decay products that can be found in the earth are outside layer such as rocks, mineral ores, in building supplies, air, water, food also in the human body (Unscear, 2019;HPS, 2015;Ahmed and Farhan, 2022;Farhan et al, 2020). Gamma radiance is the most dangerous and harmful source for the human body, which is released by these naturally produced radionuclides (Kuzmanović et al, 2020;Fawaz and Ahmed, 2014). Natural radioactivity can be present in varying amounts in different geological formations, contingent upon its source, geochemical climate, and rock type.…”

“…When inhalation via the digestive system, it has a double influence, as uranium is a heavy metal, also a radioactive metal (WHO, 2001). Raw material's radioactivity relies upon the minerals utilized in their manufacture (Kuzmanović et al, 2020). For instance, Ceramic tile radioactivity relies upon the radioactivity of the raw materials utilized in their manufacture (feldspar, bauxite, dolomite, kaolin, quartz, sand, glazes, white mud, red mud, and black mud) (Luo et al, 2017 andAl-kubaisi andFarhan, 2018).…”

In the present study, The High-Purity Germanium system was utilized to Radionuclide concentrations of 10 specimens of raw materials utilized in the ceramic manufacture from the ceramic plant in Anbar, western Iraq. The concentrations ranged between 15.035-31.410, 11.330-33.870, 85.380-272.320 Bq/kg of 238U, 232Th and 40K, respectively, with an aggregate rate of 23.523±4.121, 23.616±5.308, 176.084±58.848 Bq/kg, respectively. The radiological aspects Were discussed by computing the gamma radiance parameters. Consequently, the qualitative activity level and gamma radiance parameters are less than the authorized Global Rate's worth of US Environmental Protection Agency (US EPA) standards. The prospective source of 238U, 232Th, and 40K in raw material specimens Has contained specimens a small number of radioactive minerals like monazite, chromite, zircon, tourmaline, titanite, and apatite, there are no appreciable radiation hazard indices to personnel's in the raw material department of the study region. The research recommends proposing new Iraqi standards that specify the permissible percentages of qualitative activity concentration also gamma radiance parameters to preserve the environment and human health, especially that the ceramics plant is located in Al-Anbar center.
