ABSTRACT=<p>The use of <italic>Phyllanthus emblica</italic> (gooseberry) leaf extract to synthesize Boron-doped zinc oxide nanosheets (B-doped ZnO-NSs) is deliberated in this article. Scanning electron microscopy (SEM) shows a network of synthesized nanosheets randomly aligned side by side in a B-doped ZnO (15 wt% B) sample. The thickness of B-doped ZnO-NSs is in the range of 20–80 nm. B-doped ZnO-NSs were tested against both gram-positive and gram-negative bacterial strains including <italic>Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumonia,</italic> and <italic>Escherichia coli</italic>. Against gram-negative bacterium (<italic>K. pneumonia</italic> and <italic>E. coli</italic>), B-doped ZnO displays enhanced antibacterial activity with 26 and 24 mm of inhibition zone, respectively. The mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), mean free path (MFP), half-value layer (HVL), and tenth value layer (TVL) of B-doped ZnO were investigated as aspects linked to radiation shielding. These observations were carried out by using a PTW<sup>®</sup> electron detector and VARIAN<sup>®</sup> irradiation with 6 MeV electrons. The results of these experiments can be used to learn more about the radiation shielding properties of B-doped ZnO nanostructures.</p>
