COMPARISON OF SHIELDING STRENGTH FOR LEAD, COPPER AND ALUMINUM
Abstract
- Human safety and structural material that may be compromised from radiation exposure are vital concerns in nuclear technology. Gamma attenuation coefficient of shielding material is measured using a proper electronic system under condition of narrow beam geometry. The radiation shielding characteristics of three elemental materials were examined by using half thickness method. From the experimental data, it is found that while only 0.6cm thickness of lead is required to reduce the gamma photon intensity to half of its original value, about 1.2 cm of copper and 1.8 cm of aluminum. To achieve this goal, linear attenuation coefficient of these samples was calculated. It is cleared that lead has a far better absorber of gamma photon than copper and aluminum. In this research, comparing shielding strength of the three elemental materials, it is concluded that lead is the best as copper is the second and aluminum is the third.
