The transmission factors used to calculate radiation shielding around an industrial x-ray device are determined using the MCNP6 code. The transmission factors are given for high voltages ranging between 120 and 800 kV for lead and between 200 and 800 kV for concrete. In view of the high usage intensity of industrial devices, the transmission factors are evaluated up to 1.10-10. The parameters used in the classic equation of Archer et al are derived from the transmission data calculated here. This type of data exists in the literature, but only for voltages lower than 150 kV to meet the design demands for facilities used in the medical field. In addition, this study markedly supplements the existing data, in particular for industrial and research installations.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
