RADIATION SAFETY PROCEDURES FOR FLOODED MEMBER INSPECTION USING GAMMA TRANSMISSION TECHNIQUE: A COMPREHENSIVE REVIEW

Abstract

This paper provides a comprehensive review of radiation safety procedures in Flooded Member Inspection using the gamma transmission technique, a key nondestructive testing method in offshore oil and gas industries. This technique involves utilizing high-energy gamma-emitting isotopes, specifically Cobalt-60, to assess the integrity of submerged structures. The associated risks of using such radioactive materials demand the strict adherence to safety protocols to protect personnels, equipments, and the environment. This review outlines the methods for preparing, handling, transporting, and storing radioactive sources, emphasizing the importance of the As Low As Reasonably Achievable principle in minimizing radiation exposure. Additionally, the paper discusses the caculated foundations of radiation protection and dose management, illustrating how these principles ensure compliance with international safety standards. The results underscore the effectiveness of existing safety measures and provide recommendations for improving radiation protection practices in the FMI operations, having implications for enhancing offshore inspection safety and reliability.
