This study aims to experimentally analyze the radiation shielding capabilities of micro and nano bismuth oxide waste glasses by evaluating the effect of particle size. bismuth oxide content. and energy on the attenuation abilities of the samples. Waste glasses were powdered and combined with varying amounts of bismuth oxide with different particle sizes to test a total of seven waste ... https://parisnaturalfoodes.shop/product-category/wild-blueberry-spread/
