The Evaluation of the Doze Rate Field of Industrial X-Ray Equipment for NDT

Abstract

Nondestructive Testing (NDT) is a non-invasive method based on physical principles used to evaluate the integrity and characteristics of materials. Its measurement methodology covers a wide range of applications of materials and structures that relate to the entire life cycle, from manufacture to use and retirement. Radiography is one of the most important and widely used NDT methods for volumetric examination. In general, Radiography Testing (RT) is a method of inspecting materials for hidden flaws by using the ability of short wavelength electromagnetic radiation (high energy photons) to penetrate various materials. The intensity of radiation that penetrates and passes through the material is captured by a radiation sensitive film. This study presents the evaluation of the dose rate field in and around the radiation beam for MHF 200D X-ray tube model, using a large interval of voltage (20 to 200 kV) and current (0.5 to 8 mA). We controlled the variables that represent the essential characteristics of beam radiation quality, such as voltage (kV), and determined the Half-Value Layer (HVL) for different values of voltage and current.
