the need for comprehensive assessments that consider various influencing factors ( Abdalsattar et al ., 2014 ; Dong et al ., 2015 ).
The results obtained reveal that the radon-222 concentration values in most samples are below the permissible limit set by the International Commission on Radiological Protection ( ICRP , 1993 ), which recommends a radon-222 concentration range of 200 to 600 Bq / m 3 for dwellings . However , it ’ s noteworthy that the radon-222 levels mentioned surpass the new reference level of 100 Bq / m 3 set by the World Health Organization in 2015 ( WHO , 2015 ).
Addressing and mitigating radon-222 exposure in the affected regions is crucial to ensuring the well-being and safety of the population . Implementing measures such as radon-222 testing , ensuring proper ventilation , and employing radon-222 mitigation strategies are essential steps in reducing the health risks associated with elevated radon-222 levels . These proactive measures contribute to creating a safer living environment and safeguarding public health in areas with heightened radon-222 concentrations ( Selim et al ., 2019 ).
The release or exhalation rate of radon-222 from the soil is influenced by the presence of radium and the soil porosity . Radon-222 exhalation rates from soil are typically higher compared to those from building materials due to the soil ’ s greater porosity . However , the radon-222 exhalation rates observed in this study are notably lower than the world average
