“…The difference between the XCOM and the experimental results is within the acceptable limits. The results of this experiment are in accordance with the ones in [14,15]. The current research calculated the corresponding energy levels and the obtained result is shown in Figure 18.…”

“…To design an effective shielding, a precise knowledge of the properties of shielding materials such as radiation attenuation coefficient is needed . Some studies showed that using material with high atomic number and high density (such as iron, barite, and lead) affect significantly the shielding effect against X‐rays . These materials work very well in combination with concrete, which intrinsically possesses the ability to attenuate radiation.…”

“…2 Some studies showed that using material with high atomic number and high density (such as iron, barite, and lead) affect significantly the shielding effect against X-rays. [3][4][5][6][7][8][9][10][11][12][13] These materials work very well in combination with concrete, which intrinsically possesses the ability to attenuate radiation. However, heavy aggregates can lead segregation and bleeding effects, with a great expenditure of energy during the vibration and compaction.…”

“…As características de atenuação destes materiais são essenciais para a construção das paredes (SHIRMARDI et al, 2013). Dessa maneira, em instalações que contêm equipamentos que emitem radiações, as portas, as paredes, as janelas, o piso e o teto devem conter espessuras cuidadosamente calculadas, a fim de garantir a radioproteção do público e dos IOE contra exposição desnecessária à radiação (NCRP, 2004;ALMEIDA JR et al, 2017).…”

“…Ao percorrer a base de dados Google Acadêmico utilizando o descritor "radiological protection"proteção radiológicaforam encontrados 709 mil resultados. Porém, ao adicionar os descritores "structural shielding"blindagem estrutural -AND "bricks"tijolos -AND "Monte Carlo" AND "interventional radiology"radiologiaeste número decresce (METZGER et al, 1993;SHARIF et al, 2013;SHIRMARD et al, 2013; ALMEIDA JR, 2014; ALMEIDA JR et al, 2014; DICKSON e HAMBY, ALMEIDA JR et al, 2016, ALMEIDA JR et al, 2017SAYYED et al, 2017 (SANTOS et al, 2009). Isso sugere que a NCRP 147 (NCRP, 2004) adota uma postura mais conservadora ao considerar a grandeza kerma nos cálculos de blindagem.…”
