“…Under standard conditions, it is gaseous and easily inhaled, therefore causing a health hazard. The exposure level to radon gas differs from place to place (El-Gamal et al 2019;ICRP 2014;Lecomte et al 2014;Salaheldin et al 2019Salaheldin et al , 2021Salaheldin et al , 2020aGünay et al 2019). It is a dangerous contaminant that affects indoor air quality worldwide.…”

The present work deals with radon pollution arising from granitic rocks using an Alpha Guard radon monitor. Forty-four granitic samples were collected from five sites located in the Central part of the Eastern Desert of Egypt. The minimum to maximum concentration of radon for the rocks of Gebel (mountain) El-Missikat MS, El-Gidamy GD, RieEl-Garra RG, El-Aradiya AR, and Kab-Amira KA were 49,597 ± 8773 to 236,029 ± 22,397 Bq m−3, 39,658 ± 8341 to 188,666 ± 20,545 Bq m−3, 39,854 ± 7645 to 91,393 ± 13,429 Bq m−3, 45,951 ± 9488 to 121,935 ± 14,869 Bq m−3, and 33,209 ± 6989 to 251,398 ± 25,759 Bq m−3, respectively. The surface and mass exhalation rates, the emanation coefficient, and annual effective dose (indoors) were calculated for all the studied samples. The average value of radon concentration in the collected samples was higher than the national reference level of 300 Bq m−3 recommended by ICRP corresponding to an annual effective dose of 4 mSv at work and 14 mSv at home. The measured values for the rock samples studied in the five sites surpassed the world average of soil in areas with normal levels of radioactivity. The MS granitic samples showed a potential radiological risk for human beings, therefore, it is important to carry out a detailed monitoring program for dose assessment.

This study was conducted to evaluate the radioactivity level in the granite building raw material production area in Cenxi, China. Natural radionuclide concentrations, γ absorbed dose rates (ADRs) and radon exhalation rates were measured in the area. The spatial distribution of natural radionuclides, γ ADR and radon exhalation rate were mapped with GPS information. The radioactivity levels in the study area were analysed based on the descriptive statistics and frequency distribution of measurement data. According to the Chinese standard, the granite raw materials used for building and decoration in this region were classified based on their radiological hazards. In addition, radiation protection measures were proposed for the mining of local granite building materials products as well as environmental protection around the work area and resident safety.
