Abstract :
The ionizing radiation usage makes important to develop protection against the possible damaged caused to patients and exposure workers. That way we can optimize the benefits of this applied technique and minimize the risk. Different authors use to publish about the transmission curves as a function of shielding material thickness. However, they limit their data to few curves and do not cover all the options needed to get closer to the reality. As results we got transmission curves considering different spectra energy to concrete, barite concrete and barite mortar. The simulated data were organized in graphics built using Originreg software. These data was used to generate a data bank applied to diagnostic radiology shielding estimating, presenting curves of transmission as a function of shielding thickness and shielding thickness as a function of transmission. All simulations data variations and errors were considers a good approximations to this kind of application according the bibliography. We suggest new works considering another material used to build diagnostic radiological shielding in Brazil and different spectra energy applied to different diagnostic radiology area.
