The Effect of Iron Fillings Waste Contents on the Attenuation Level of Anti-Radiation Shielding Concrete

Abstract:

Shielding concretes of different iron filling contents were assessed for their anti radiation attenuation properties. The measurements have been performed by using gamma spectrometer of NaI (Tl) detector, the sources were Cs¹³⁷ and Co⁶⁰ radioactive elements with photon energies of o.662 MeV, for Cs¹³⁷ and the two 1.17MeV, 1.33 MeV energy levels for the Co⁶⁰. Likewise, the mean free path of the tested samples was obtained as well. From the measurement of the linear attenuation coefficients for these different shielding materials, it was found that as the iron filings within the concrete are increased the linear attenuation coefficient is increased also. It can be concluded from this work that the Iron filings content in concrete is very effective in augmentation of the anti-radiation shielding capability. It can be used as shelters material for secure storing of the nuclear wastes.
