Gamma Radiography is a non-destructive testing technique that uses gamma rays to inspect materials and structures for defects. It involves placing a radioactive source near the object being examined, which emits gamma radiation that penetrates the material. A detector captures the radiation that passes through, creating an image that reveals any internal flaws. This method is commonly used in industries such as oil and gas, nuclear power, and construction to ensure safety and quality. Gamma radiography is effective for inspecting welds, pipes, and other components, helping to identify issues before they lead to failures or accidents.
