Abstract (Abstrak)

The flexible and transparent film for X-ray radiation shielding have been fabricated successfully in the form of composites PVA/Gelatin/BaCO3/transparent wood. The wood samples were delignified for 3, 6, and 9 h to remove the lignin content. Beer-Lambert equation was used to calculate the shielding parameter based on the thickness of the sample and the intensity before and after applied all energy irradiation considered. FTIR and X- ray shielding test confirmed that the shielding able to absorb most of photon energy and well-interacting with atoms in samples. Low HVL shows the material was effectively block the radiation. The samples with 0.5 g BaCO3 showed the lowest HVL (0.72747 cm) compared to others composition. The linear attenuation coefficient was 1.37463 cm− 1 at 55 keV with of 0.5 g of BaCO3. The mass attenuation coefficient also confirmed that the attenuation of composites increases (ex. 55 keV irradiation energy for 0.1 g BaCO3 is 0.793, 0.941 cm− 1 for 0.3 g BaCO3, and 1.115 cm− 1 for 0.5 g BaCO3) linearly along with increasing of BaCO3 concentration and shows good agreement with theoretical calculation from XCOM database. It is indicated that the PVA/Gelatin/BaCO3/ transparent wood composites show high potentials as a new transparent and flexible shielding material for X-ray radiation application in medical sector.
