“…For all tests performed in this work, the ionization chamber was positioned in the center of the X-ray field as stated in international reports [6,15]. Corrêa et al [13] evaluated the dose distribution in an X-ray field generated by a mammography system and they found that the 3 highest dose was about 50 mm from the chest wall. So, the ionization chambers utilized in this work had their sensitive volume center located at this position for all radiation equipment employed in the current investigation, instead of the common distance of 40 mm.…”

“…Analisando a Figura 3, o perfil de distribuição do campo de radiação do mamógrafo está dentro do esperado, podendo ser observado o Efeito Heel causado pela posição catodo-anodo do arranjo do mamógrafo. Esse mesmo comportamento foi obtido experimentalmente por Corrêa et al (2013), utilizando dosímetros de CaSO 4 :Dy.…”
