“…Additionally, the values of l m irregularly decrease with photon energies (0.662 MeV 6 Eg. 6 1.333 MeV) for M1 and M4, which indicates the different photon absorption mechanism for different photon energies [16]. With regard to gamma-ray shielding, the percentage of slag in mortar increases the density of the sample, because the mixes with slag have high iron content.…”

“…The shorter mfp indicates more interaction of photons to material and hence possesses the better shielding properties [16], and that it is the reciprocal of the measured linear attenuation coefficients. In this investigation, the variation of mean free path (mfp) as a function of the samples thickness for the two mixes M1 (control mix) and M4 (incorporating 100% slag) was measured at different photon energies of 0.662, 1.173 and 1.333 MeV.…”

In the present study, the effects of replacing sand by high percentages of basic-oxygen furnace slag on the compressive strength, bulk density and gamma ray radiation shielding properties of mortar have been investigated. Cement mortar of mix proportion 1:3 including various percentages of iron slag was designed. The percentages of replacement were 0%, 40%, 80% and 100% by weight of fine aggregate. Mortar mixes were prepared with water cement ratio of 0.44 and cured in potable water for 90 days. The attenuation measurements were performed using gamma spectrometer of NaI (Tl) detector. The utilized radiation sources comprised 137 Cs and 60 Co radioactive elements with photon energies of 0.662 MeV for 137 Cs and two energy levels of 1.17 and 1.33 MeV for the 60 Co. Likewise, half value layer (HVL), tenth value layer (TVL) and the mean free path (mfp) for the tested samples were measured. Results of this investigation indicated that the strength properties of mortars increased significantly upon replacing sand partially by iron slag. It was also observed that the inclusion of iron slag as partial replacement with fine aggregate enhances the bulk density of mortar. On the other hand, full sand replacement by iron slag has significant effects on shielding efficiency in thick shields, as it reduces the capture gamma rays better than normal mortar incorporating sand. ª 2015 The Authors.

“…Although successfully obtained glasses with good properties, bismuth produced yellow color in glass which can found no use (or little use) as glass imitation gemstone. Bi 2 O 3 were also used for replacing PbO in radiation shielding glass materials [16][17][18][19][20].…”
