Preparation and characterization of polylactic acid-based composite incorporating with BaSO ₄ for low radiation dose shielding

In radiology it is necessary to use protective devices in radiological work to reduce the negative health effects of radiation. The objective of this study is to investigate an alternative lead-free radiation shielding material from PLA composite with BaSO4 and assess its efficacy in providing radiation protection. The findings indicate that the PLA composite containing 30% BaSO4 exhibited the most effective radiation absorption properties, with percentages of 92.15%, 89.26%, and 86.04% at X-ray energies of 40, 60, and 80 kVp, respectively. Moreover, the PLA composites containing BaSO4 are environmentally friendly providing suitable protection against low-dose radiation
