AB  - Sheets of high-density polyethylene (HDPE) loaded with magnesium oxide in micro 
      and nano were synthesized with different weight percentages of micro-MgO 
      (0,5,10,20 and 30% by weight) and nano-MgO (5 and 30%) and shaped in form of disc 
      and dog bone shape. The morphological, mechanical, and attenuation 
      characteristics of each concentration were determined. The linear attenuation 
      coefficients (LAC) of the prepared discs were calculated using a well-calibrated 
      scintillation detector and five standard gamma-ray point sources ((241)Am, 
      (133)Ba, (137)Cs, (60)Co and (152)Eu). The LAC was theoretically calculated for 
      HDPE/micro-MgO composites using XCOM software. A good agreement between the 
      theoretical and experimental results was observed. The comparison between micro 
      and nano-MgO as a filler in HDPE was evaluated. The results proved that the 
      loaded nano-MgO in different proportions of HDPE produced greater attenuation 
      coefficients than its micro counterpart. The addition of nano MgO with different 
      weight percentage led to a significant improvement in the mechanical properties 
      of HDPE, the ultimate force and ultimate stress increased as the concentration of 
      nano MgO increased, and the young modulus of HDPE also increased with increasing 
      concentration of micro and nano MgO.
