Discussion

Study explores enhanced radiation shielding with rare earth elements and composites, suggesting improved safety.

The study reveals that composites with rare earth elements provide better radiation absorption than traditional materials.
Simulations confirmed the mass attenuation coefficients of bismuth and lead aligned closely with NIST values, varying by less than 2%.
Various shielding materials were modeled using Monte Carlo simulations to determine their effectiveness in radiation protection.
Findings highlight that four composites with rare earth elements outperformed bismuth and lead in the 50–80 keV energy range.

Şişman et al. (2025) studied this question.
