“…In all European nations, the allowable effective dosage from occupational radiation dose is 20 mSvy -1 , whereas, in the United States, it is 50 mSvy -1 . In this regard, the obtained results are in agreement with the literature published data for the similar environment of different countries [3,13,[26][27][28][29][30][31][32][33][34][35][36]. Figure (4) shows a comparison between radon concentration results for NTD, sample (N3) that has a high value of radon concentration due to increasing content of 238 U and 226 Ra activity concentration; on the other hand, sample coded (S1) has a low value of radon concentration due to low level of 238 U. R* = Reference of permissible limit dose volume of the container, the surface area of the sample, and the radon decay constant.…”

The Sukari granitoid pluton, namely the Sukari gold mine (SGM), located in Egypt's southeastern desert, is outstanding gold-bearing granite in the Arabian Nubian Shield. CR-39 and LR-115 Nuclear Track Detectors (NTD) were used in the present study to determine radon concentration, after which the exhalation rate, annual effective dose, and work level were calculated. The overall average radon values from the CR-39 and LR-115 NTD are 11.27 and 11.29 kBqm -3 , respectively, indicating a consensual correlation that depends on the charged particles, particularly accumulation radon gas emissions from investigated samples measured by Nuclear Track Detectors. The findings revealed a significant quantity of NORM in the SGM due to the radon concentration which is greater than the IAEA, ICRP, and UNSCEAR recommended limit of 1000 Bqm -3 . The present study aims to evaluate and predict the radioactive changes in the investigation area, assess dangerous radiation, and implement radiation safety standards for the workers in the SGM. The current research may also be useful in the future investigation and mining of nuclear materials for optimization business in the SGM and its surrounding area.

“…Several studies have been conducted on the radon concentrations in the indoor environment and its effect on human health. [7][8][9][10][11] In order to find the indoor radiation dose received, the concentration of radon, thoron and progenies in residential places of Coonoor, South India has been undertaken. This study is a part of a systematic study of natural environmental background radiation of important places on Western Ghats in South India.…”

Indoor radon, thoron and progenies are major contributors to the indoor radiation dose which have been measured by our study for different types of dwellings during four seasons of a year. The indoor radon, thoron and progeny levels observed in the present study found to vary with seasons of a year. The average highest radon, thoron and progeny were observed during winter and the corresponding lowest values were observed during summer. The highest 222Rn, 220Rn and progenies concentrations were observed in mud houses and the lowest values were recorded in wooden houses. A good correlation with a correlation coefficient of 0.85 was observed between indoor 222Rn and concentration of its grandparent 238U in underlying soil. A moderate correlation was found between 220Rn and 232Th concentration in underlying soil. The effective dose received by the general public in the present study due to radon and thoron was estimated as 1.43 and 1.13 mSv y−1, respectively. The 222Rn and 220Rn progenies contribute 0.79 and 0.25 mSv y−1, respectively to the annual effective dose received. The inhalation dose received by the general public of the study area due to these airborne isotopes 3.69 mSv y−1 is less than the action limit of International Commission of Radiological Protection (ICRP) (2009).
