Synthesis and characterizations of magnetite–borogypsum for radiation shielding

Abstract

Nowadays, parallel to the increasing use of nuclear technology, radiation protection becomes an important issue. The use of materials, such as (Pb) lead, has become standard for protection from radiation. Improving the radiation attenuation properties of new types of materials has become more essential. In this study, the shielding properties of panels containing boron (B) waste (borogypsum) that were produced with different iron (Fe) mineral additives were studied. The attenuation properties of two types of panels produced by using magnetite and borogypsum against gamma radiation were investigated. It was found that gamma radiation protection decreases as the borogypsum contribution to the magnetite panel mixture increases. At the same time, it was observed that the linear attenuation coefficient and water absorption decrease due to the increase in borogypsum additive and sintering temperature inside the panels.

Molecular Polar Surface Area, Total Solvent Accessible Surface Area (SASA), Heat of Formation, and Gamma-Ray Attenuation Properties of Some Flavonoids

“…The behavior of TVL curve is similar to that of T 1/2 and λ at the whole considered energy level [47,48]. This supports the general variations of the transmission factors with the photon energy, such that all the transmission factors (TVL, T 1/2 , and λ) have minimum values at low energies and then they increase as the photon energy increases, reaching their maximum values at the high energy level [49]. Figure 7 describes the attenuation properties of the investigated flavonoid samples in terms of effective atomic number (Z eff ) as a function of energy up to 15 MeV.…”

“…On the other hand the radiation requires extreme care due to its hazardous effect to human cell. Thus radiation dosimetry becomes important in science and new techniques, materials have been under study to develop as alternative to conventional materials [1][2][3][4][5][6][7][8][9][10][11]. The neutron with the proton is an important particle in nuclear physics and due to neutral character its shielding is more difficult than others.…”

“…Thus, it is required to protect workers, patients, and the general public from this hazardous effect of ionizing radiation. The protection may be done using three ways of reducing exposure time, maximizing distance from radiation source and use shielding materials to reduce this unwanted radiation [6][7][8][9][10][11][12][13]. Radiation shielding is the most effective way in others and conventionally used shielding material is lead and lead based materials.…”
