Size-controlled Gd2O3 nanospheres reinforced B4C/HDPE nanocomposites for neutron and gamma-ray complex radiation shielding

Key Points

• The incorporation of gadolinium oxide nanospheres significantly improves radiation shielding effectiveness against both neutrons and gamma-rays.
• A specific size-controlled formulation of Gd2O3 shows a marked increase in neutron attenuation by up to 30% compared to traditional materials.
• Nanocomposite materials were produced using a combination of boron carbide and high-density polyethylene, yielding enhanced protective properties.
• These findings indicate better shielding options for various applications, including nuclear energy and medical imaging, though further tests may be needed.
