“…The average indoor radon concentrations of both towns are below the IAEA's recommended level of 300 Bq/m 3 . It is comparable with countries with warmer climates, such as the Israel (Epstein, Koch, Riemer, Orion, & Haquin, 2013) and some Arab countries (Al-Azmi et al, 2012) A characteristic of a lognormal distribution is that the natural logarithm of the data will exhibit a normal distribution (Limpert, Stahel, & Abbt, 2001). As can be seen from Figures 8 and 9, both datasets exhibit this characteristic.…”

Granite commonly contains high concentrations of uranium, with subsequent high exhalation of radon gas. The geology of the West Coast Peninsula of South Africa is dominated by granite. No measurements of radon gas has, however, been undertaken in, or near the towns of the peninsula and a recent article predicted potentially high indoor radon concentrations in the town of Saldanha. This article sets out to validate the predicted results by measuring the indoor radon concentration for the two largest settlements on the West Coast Peninsula: Vredenburg and Saldanha. Measurements were conducted during the summer months with houses typically being more open due to the warm weather. The data was found to exhibit lognormal behavior, with the I-type granite formation of Vredenburg yielding a higher indoor radon concentration than the ignimbrite formation of Saldanha. The average indoor radon concentration of Vredenburg was 34% higher than that of Saldanha, with 58.7 Bq/m 3 and 38.6 Bq/m 3 respectively.

“…The novelty of the results obtained in the current study is that it is a commentary to the recent studies bout radioactivity in Saudi Arabia Kingdom [ 19 , 20 , 21 , 22 , 23 ]. Where the building imparted some radiation dose to the human beings [ 21 ]; the average value of 222 Rn obtained in our current study agrees with that reported by Al-Ghamdi et al. [ 24 ].…”

In the present study, six water samples were collected from different locations in the Kingdom of Saudi Arabia and another sample from the Zamzam site in Makkah city. The concentration of the radioactive isotope 222 Rn was measured using the electronic radon detector (RAD7). The comparative analysis study on these samples showed that the average concentration value in all samples was 0.504Bq/L. The data analysis showed that the concentration of 222 Rn was ranged from 0.43 AE 0.06 Bq/L to 0.57 AE 0.060 Bq/L for all samples. These levels are below the contamination threshold (11.1 Bq/L) recommended by the US Environmental Protection Agency (EPA). Interestingly, Radon radioactivity levels were lower than those harmful to human health. The principal component analysis (PCA) using (SPSS version 15) was used to reduce the four variables influencing the 222 Rn activity concentration to two variables: temperature (correlation coefficient, R 2 : 0.984) and the relative humidity (RH%) (R 2 :-0.987). The increase in temperature reduces the solubility of 222 Rn gas activity water and facilitates its detection, whereas increased the RH% increases its solubility and decreases the detection level of 222 Rn activity concentration. The interaction between temperature and RH% does not affect the concentration of 222 Rn.

“…The results of the surveys showed that radon concentration levels in most of the dwellings averaged from 30 to 204 Bq m −3 , depending on the detector location (country), whilst in some old cities, and in an area close to a phosphate mine, the levels were found to be relatively high (>300 Bq m −3 ) [106].…”

Indoor radon is a major hazard to human health; it is one of the leading causes of lung cancer. Therefore, radon research in Asia has intensified recently due to the growing awareness of the harm that radon poses. An analysis of the collected literature data showed that in Asia–Oceania, some regions have—or are believed to have—little indoor radon problems due to climate and low Rn ground. It can be concluded that countries have their own approaches, techniques, and protocols. Data were not harmonized within each region; however, measurement techniques were compared by regional intercomparison exercises. The situation differs regarding studies on the usability of radon as a tracer or potential predictor of tectonic phenomena, as some countries are in seismically active zones, such as India, Taiwan, China, Japan, etc. India and Taiwan are global leaders in this research, as well as Italy, which is another seismically affected country. We provide an overview of radon-related surveying and research activities conducted in the western, southern, and eastern Asian regions over the past few years. Additionally, we observed that the number of indoor radon measurements per million inhabitants increases as the human development index (HDI) increases.
