Abstract

In this research, the calculation of the Attenuation of X-Ray for low density polyethylene composites with Walnut shells powder. Low density polyethylene (LDPE) production by the State Company for Petrochemical Industries (Basra-Iraq), the range of the added of Walnut shells powder have the values 2.5%, 5%, 10%, 15%, 20%, and 30% for low density polyethylene weight ratio and the added Walnut shells powder with the particular size (≤ 250 μm), whereas the practical study was by using the beam of X-Ray at (33 kV) and operation voltage of Geiger–Müller tube was (VG.M = 600 Volt) . The results showed increasing fillers content leading to an increases the total linear attenuation coefficient, while the mean free path decreases. The path rate (λ) at 5% is 18.5 cm, while at 30% is 2.5 cm. The value of the linear attenuation coefficient (μ) at 30% it is 0.4 cm^-1, while it is 0.054 cm^-1 at 15%.
