Resumo
Resin-based materials equivalent to water were developed and four different samples were obtained. The linear
attenuation coefficients of all samples was evaluated using X-ray spectrometry with primary and transmitted
beams using voltages at the ranging from 60 to 120 kV. The experimental measured values were compared with
theoretical reference values to water and with that obtained using the Least Square Method algorithm methodology
(method applied to diagnostic radiology and radiotherapy). Our results show that differences between
the measured values and the target μ(E) was lower than 7% ± 0.3 in the energy range from 20 to 80 keV. These
results enable to consider that the material developed and produced is a good option to be used as a waterequivalent
material and the experimental method adequate to its quantitative evaluation.
