This study aims to comprehensively evaluate the results of radon gas measurements in buildings and concrete, which is the most consumed material globally, over the last 40 years. It also addresses the gap in the literature by determining which parameters affect the relationship between radon, concrete, and buildings. Radon, known as the "invisible killer," is the second leading cause of lung cancer after smoking, responsible for 3-14% of lung cancer cases worldwide. The study found that radon concentration limits in houses range from 100-400 Bq m⁻³, and in workplaces, from 100-3700 Bq m⁻³. Radon exhalation rates in concrete vary from 0.23-510 Bq m⁻² h⁻¹, and indoor radon concentrations range from 4.6 to 583 Bq m⁻³. Despite existing literature, there is a need for improved and widely accepted protocols for measuring radon exhalation rates in construction materials and indoor radon concentrations in buildings. The article reviews radon sources, its formation, and its effects on human health, highlighting the importance of concrete in radon transmission and the need for better measurement techniques.This study aims to comprehensively evaluate the results of radon gas measurements in buildings and concrete, which is the most consumed material globally, over the last 40 years.
