Evaluating radon gas emissions in the Jazan region along the Saudi coast

Individuals frequenting beaches are exposed to different levels of radiation exposure. This study aims to assess the levels of radon gas along of the Red Sea beaches, specifically in the Jazan region of Saudi Arabia. The levels of radioactive contamination were measured using a CR-39 detector. According to the results, the southern Corniche Beach in Jizan had the highest concentration of radon gas at 541.13 ± 34.62 Bq/m 3 . In Farasan Island, the highest radon concentration was recorded 416.25 ± 30.29 Bq/m 3 at Al Qasim Beach. Analysis of annual effective dose data revealed that 9% of measured dose levels exceeded the maximum permissible limit. However, uranium and radium concentrations were found to be within internationally accepted safety thresholds. Most beaches in Jazan and Farasan Island were identified as radiologically safe. However, continuous monitoring of sites with elevated values is recommended to prevent potential increases in radiation levels. This research contributes valuable insights into coastal radiation assessment and preventive measures, enhancing our understanding of environmental radiation exposure in coastal areas.
