What type of radiation is commonly used in radiographic testing?

In radiographic testing, X-rays are commonly used for inspecting materials and detecting internal flaws. X-rays are a form of electromagnetic radiation that can penetrate various materials, including metals and plastics, allowing for the creation of images that reveal the internal structure and potential defects within the tested material.

The properties of X-rays, such as their wavelength and penetrating power, make them particularly effective for this purpose. They can provide a non-destructive means of evaluating welds and structural integrity without damaging the components being inspected. This method is widely used in industries such as aerospace, construction, and manufacturing to ensure safety and quality standards.

While gamma rays are also a form of electromagnetic radiation that can be used in radiographic testing, X-rays are more commonly utilized due to their controlled production, lower energy levels, and ease of use in various industrial applications. Alpha and beta particles are forms of particle radiation that have different properties and applications, typically not suited for radiographic testing of materials compared to X-rays and gamma rays.
