Dose equivalent transmission data for shielding industrial x-ray facilities up to 800 kV

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.
