Abstract

This study aimed to reduce the risks of lung cancer linked to radon gas concentrations. To ensure public safety in the college and avoid the danger of radiation, and to achieve the goals of sustainable development in providing a suitable, clean, and hazard-free environment. These reasons led to research on measuring indoor radon levels in the Physics department, which is part of the College of Education at Anbar University. The study was conducted over a period of approximately 40 days, during which CR-39 detectors were exposed to indoor air in the halls and laboratories. After that, take the detectors to etching in NaOH solution at 6.0N for a temperature of 70 ± 1 °C using a water bath for 1.0 h. The radon concentration range of these areas is from (67 to 104) Bq/m3, with an average value of 76.6 Bq/m3. The radon concentration in the building was found within the recommended range. Furthermore, the annual effective dose (AED) and the cancer risk factor related to chronological age were both below the recommended limits. It highlights the importance of ensuring a healthy environment for all students and staff. When comparing the radiation levels of the samples investigated with internationally accepted values, the current results showed that they were within permissible limits.
