Manufacturing and performance evaluation of medical radiation shielding fiber with plasma thermal spray coating technology

Abstract Lead, which has been used for radiation shielding in medicine, is currently sought to be replaced by an eco-friendly shielding material. Therefore, it should be replaced with shielding materials possessing excellent processability and radiation shielding performance similar to that of lead....
