Determination of Natural Radioactivity: A Case Study in Wadi Muhrim, Taif, Saudi Arabia


The current study evaluates the dose rates and risk impact of the concentration of natural radioactivity for 238U, 226Ra, 232Th, 222Rn, 228Ra, and 40K as well as cosmic ray to establish guidelines and rules pertaining to habitat, agricultural products, and building materials sourced from these areas. It also maintains data records and radiological maps of the area to identify potential future changes in the environmental radioactivity. Over the past few decades, Saudi Arabia’s population has increased significantly, driving up demand for housing property. Some locals made the decision to construct their homes amidst mountains and valleys, as those in the Wadi Muhrim area of the Taif region. The soil and rocks in a few of these areas contain incredibly high quantities of natural radioactivity. Natural sources of this radioactivity include the 235U, 238U, and 232Th series, natural 40K, the gas 222Rn, and its radioactive offspring. Cosmic rays are mostly produced by the galactic and extragalactic discs. Recent research has been done in the region to monitor these radio-ecological components and to carry out case-control studies. The author researched the area and produced radiological maps for the soil, water, and air in order to pinpoint the locations with the highest radiation levels. Investigations included dose evaluations of the public health in order to develop rules and regulations governing habitat, agricultural products, and the usage of building materials from these sites. In order to have a complimentary and comprehensive conclusion for the findings in our study, it will be highly helpful to carry out the same investigation in other regions of the kingdom with similar geology patterns.
