Popis: Exposure to high concentrations of radon gas is the leading cause of lung cancer for nonsmokers according to the World Health Organization (WHO) figures. With poor ventilation standards and lack of awareness among Jordanians, constant monitoring of radon concentrations is vital. Multiple efforts have been made since the 1990s in order to create a national radon map of Jordan, by acquiring average values of radon concentrations in major Jordanian cities. This study aims to replicate those efforts using a more accurate and modern way of detection for the purpose of comparing the current values with literature values and to update the previous radon concentration map of Jordan. The study concludes that radon concentrations in Jordan have mostly increased in the past 30 years from an overall average of 52 Bq/m3 to an average of 60.4 Bq/m3. Despite the increase, these results are considered under the threat line that is estimated conventionally by most of the international environmental and radiation-related organizations, which is 100–300 Bq/m3. It should be noted that only the Russeifa city has scored a value higher than the estimated threat line. This is due to the existence of abundant phosphate mines filled with condensed radon levels leaking from these ores. It is expected that radon concentrations in Jordan will increase in the coming years with the continuous urban sprawl and lack of public awareness about the radon gas health issue. A number of suggestions have been proposed in this study that could help the Jordanian society avoid a future possible health threat.
