“…Furthermore, the mass attenuation coefficient of a commercial lead apron at 40 keV was 7.0 cm 2 ·g –1 , which was remarkably lower than that of Bi 28.2 @Bi 3.48 La 3.38 –NL (18.9 cm 2 ·g –1 ). 8 Previous literature reported that the mass attenuation coefficient of the fabric-based X-ray shielding material was 9.6 cm 2 ·g –1 , which was also uncompetitive if compared with Bi 28.2 @Bi 3.48 La 3.38 –NL . The comparison in the attenuation coefficient suggested that the prepared NL-based composite exhibited outstanding performance in X-ray shielding.…”

The X-ray shielding performance comparison of the NLbased composite and polymer-based materials was also conducted, which indicated that the X-ray shielding ability of Bi 1.51 La 1.51 −PDMS and Bi 1.51 La 1.51 −ER was remarkably lower than that of Bi 1.51 La 1.51 −NL and Bi 28.2 @Bi 1.51 La 1.51 −NL (Figure S13).…”

A high-shielding, low secondary radiation, lightweight, flexible, and wearable X-ray protection material was prepared by coimpregnating La 2 O 3 and Bi 2 O 3 nanoparticles in natural leather (NL) with an additional Bi 2 O 3 coating at the bottom surface of the leather. The prepared Bi 28.2 @Bi 3.48 La 3.48 −NL (28.2 and 3.48 mmol•cm −3 are the loading contents of elements) showed excellent X-ray shielding ability (65−100%) in a wide energy range of 20−120 keV with reduced scattered secondary radiation (30%). The bottom surface coating played a critical role in enhancing the X-ray attenuation and reducing the scattered secondary radiation by reflecting and deflecting incident X-ray photons. Excellent mechanical property with superb bending resistance of the NL matrix was properly maintained, and its tensile strength and tearing load were 15.39 MPa and 25.81 N•mm −1 , respectively. This lightweight and wearable high-performance protection material can facilitate safety and comfortability during intensive activities of practitioners in the health care industry.

“…This method has the disadvantage of not imparting the inherent properties of the fibers to the fabric because of their low flexibility and high rigidity [37][38][39]. In addition, it is difficult to reproduce the shielding performance because the shielding performance must be controlled by adjusting the coating thickness during the process [40,41].…”

As the scope of radiation use in medical and industrial fields has expanded, interest in radiation shielding is increasing. Most existing radiation shields use Pb-based products, primarily in the form of a laminated sheet, which requires attention as fine cracks may occur depending on the usage and storage conditions. The weight of the sheets limits users’ activities, and they pose a risk of heavy metal contamination. To address these problems, this study proposed a shielding fiber with improved flexibility and workability, and thus, produce a shielding garment. Masterbatches of polyethylene terephthalate (PET) fiber were manufactured using the eco-friendly materials, BaSO4 and Bi2O3. Yarns were fabricated by the melt spinning process, and fabrics were woven. With 5 wt% of shielding material, the yarns’ shield against radiation and was sufficiently strong for fabric weaving. The fibers’ radiation shielding averaged 9–13%, with the Bi2O3 fiber displaying better shielding performance than the BaSO4. It is believed that the findings of this study on improving the yarn manufacturing process could be applied for protection against low-dose and scattered rays in medical applications and for aerospace radiation protection. In addition, the proposed shielding fibers’ flexibility makes them suitable for future use in the production of various radiation shields.

“…Therefore, if the thickness of the shielding sheet is fixed, the linear attenuation coefficient, which is a function of the radiation energy, can be calculated using Equation (1). In a shielding sheet with a constant thickness, medical radiation energy is inversely proportional to the shielding efficiency, and the higher the intensity of the incident energy, the lower the shielding efficiency [27]. As a result, the greater the interaction due to the dispersion of oyster shell powder particles in the shielding sheet, the greater the shielding efficiency owing to the attenuation of the radiation energy.…”

As radiation-based techniques become increasingly important tools for medical diagnostics, medical professionals face increasing risk from the long-term effects of scattered radiation exposure. Although existing radiation-shielding products used in medicine are traditionally lead-based, recently, the development of more eco-friendly materials such as tungsten, bismuth, and barium sulfate has drawn attention. However, lead continues to be superior to the proposed alternative materials in terms of shielding efficiency and cost effectiveness. This study explores the feasibility of radiation shielding materials based on the shells of bivalve mollusks such as oysters that are discarded from aquaculture, thereby preventing them from going into landfills. In addition, a firing process for enhancing the shielding efficiency of the original material is proposed. Experiments show that shielding sheets comprising 0.3 mm thick layers of oyster shell achieve a shielding efficiency of 37.32% for the low-energy X-rays typically encountered in medical institutions. In addition, the shielding efficiency was improved by increasing the density of the powdered oyster shell via plastic working at 1200 °C. This raises the possibility of developing multi-material radiation shields and highlights a new potential avenue for recycling aquaculture waste.
