Radiation protection for well logging operations in Saudi Arabia.

This article focuses on radiation protection requirements for well logging operations involving nuclear logging tools in Saudi Arabia. Nuclear logging tools contain sealed radioactive sources, such as Cesium-137, Cobalt-60, and Americium-241/Beryllium, used to evaluate geological formations during hydrocarbon exploration. The International Atomic Energy Agency (IAEA) provides international safety standards, while the Saudi Nuclear and Radiological Regulatory Commission (NRRC) oversees licensing and regulatory compliance for radiation safety in these operations. The article outlines industry best practices for handling, transporting, and storing radioactive sources, procedures for recovery if tools become stuck, and protocols for the abandonment of radioactive sources in wells, including immobilization with red cement and marking with identification plaques to ensure long-term safety.
