Abstract:
ABSTRACT Linear attenuation coefficient was measured experimentally and calculated for both pure silicone, and silicone supported with lead. Two sizes of lead particles have been used 300 μm and 600 μm.The attenuation coefficients have been measured experimentally using slices of thickness (0-5) cm. Moreover, gamma radiation source have been used 137Cs (E􀀀 = 0.66 Mev) together with scintillation detector NaI (Tl). The results showed that the attenuation coefficient of silicone with lead additive is greater than the attenuation coefficient of silicone alone.Besid that, it is found that the attenuation coefficient of silicone with lead additive of size 300 μm larger than that with lead additive of large than size 600μm. Key words: attenuation coefficient, gamma source, NaI detector.
