Gamma-ray shielding properties of concrete including barite at different energies

Developments in nuclear technology in the last century have lead to the use of radiation in different areas of human activity. These are not just the energetics but also food, agriculture, medicine, industry and science. Thus, radiation has become an inevitable phenomenon in our lives. Since we cannot isolate radiation from our life, the radiation protection methods should be available. As alternatives to conventional radiation prevention methods, such as lead and heavy concrete shielding, more functional materials need to become the focus of research. The development of the least harmful to the environment, easily applicable, flexible radiation shields has become very important. In this study, silicon matrix composite panels, doped with different ratios of barite and boron carbide, were produced and characterized by optical and scanning electron microscopy (SEM). Gamma and neutron radiation shielding properties of these materials were investigated. The results have been compared with the lead as the standard shielding material.

In this study, the radiation absorption properties of mortars and plasters used in historical buildings have been investigated. Studied lime concretes contained such additives as brick dust, fertilizer, wet lime, wool, egg white, bone meal, rice, casein, whey, bone ash and tree leaf juice, in different concentrations. The linear attenuation coefficients of gamma rays in lime concretes have been measured at 662, 1773 and 1332 keV. The gamma rays have been obtained from 137 Cs and 60 Co sources and the measurements have been performed using a gamma spectrometer, based on a 3 × 3 NaI(Tl) detector, connected to 16384-channel multi-channel analyser.

“…Akkurt et al tested the shielding properties of concrete including Barite using Cs-137 and Co-60, individually [8]. They measured and calculated radiation shielding abilities for concretes containing various amounts of Barite in their earlier paper too [9,10].Barite has been suggested as concrete aggregate to more effectively shield against radiation.…”

Abstract. Radiology has seen enormous growth with the latest medical equipment and increase in radiation technology usage. Lead is also used to shield against radiation leakage to diminish harmful effects of radiation dosimetry to human bodies. To save harmful, cost, effective shielding and provide easy installation, a pre-cast board with fiber concrete layers and heavyweight concrete with Barite is developed. The radiation attenuation coefficients for Barite concrete board are calculated and measured in this report. This board can instead of lead for the photon energy around the diagnostic medical areas. The board has been successfully employed in medical hospitals and makes shielding easy and effective.
