| Abstract | ||||
| Nowadays, radiation shielding becomes vital. So, the main purpose of this study is to evaluate the characteristics and performance of six types of raw wood materials (Mosky, Zan, Contar, Balot, Orange tree and Aro) usually used in Egypt. Linear, mass attenuation coefficients and half value layer of wood species were measured at gamma-ray energy range from (30-2203 keV). Measurements were performed using aHPGe gamma spectrometer detector.The intensities of the emergent radiation were measured, when each of these woods were placed between the detector and radioactive sources (133Ba-226Ra). Analysis of results showed a strong correlation between wood density and attenuation coefficients. The lowest value of linear attenuation coefficient determined for each wood type is 0.040 cm-1 at energy 609 keV for Mosky. On the other hand the highest value of linear attenuation coefficient at the same energy is, 0.078 cm-1 for Aro. So, Aro could selected and serve as a more favorable radiation shielding material against gamma ray. | ||||
