INEGI reports that 81% of new constructions are built with durable materials, such as concrete blocks, including
rooms where ionizing radiation is used, such as clinics and hospitals. The volume ratios used in the manufacture
of concrete blocks have a 1: 5: 2 ratio of: portland cement, sand and crushed gravel. The percentage mass content
of each atom in the sample is obtained with the energy-dispersed X-ray fluorescence, these results are used to
calculate the characteristics such as shielding of the concrete blocks, which have been partially reported, in this
work several characteristics are presented for photons from 1 keV to 100 GeV, such as linear attenuation coefficients,
the hemireductive layer, the effective, atomic and electronic sections, the effective atomic number
(Zef). The exposure of accumulation and energy absorption factors (EBF, EABF) of 0.5–40 mfp are reported, using
the Photon Shielding and Dosimetry (PSD) software. These characteristics are compared to those of NBS concrete.
The concrete blocks have an attenuation capacity for energies used in radiological equipment such as
mammography, 20–35 keV; dental, 50–90 keV and for conventional radiography equipment, 70–150 keV, so the
block and lightened concrete block must be considered in the calculations of primary and secondary shielding
walls.
