Radiation Shielding Properties of Mortars and Plasters Used in Historical Buildings

Abstract

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.

The Effect of Lead Oxide on the Change in Gamma Ray Protection Parameters of Bismuth Oxide

“…Over the last years, efforts to find new shielding materials to replace Pb' in terms of cost and easy usability, a heavy metal, have increased. A wide variety of materials designed for use as radiation shields exist in the literature [3][4][5][6][7][8][9][10][11].…”

Determination of The Radiation Shielding Performance of MoO2 Addition On PbO by Monte Carlo Simulation

“…Especially since there are situations where distance and time cannot be prevented, shielding is done in order to shield from radiation. Concrete (or building materials) and lead materials are mostly from the shielding materials used in radiation protection [4][5][6][7][8][9][10]. Due to the toxic effect and transportation difficulty of these materials used, intensive studies are carried out on alternative materials.…”

Utilization of Marble and Boron Waste in Brick Products

“…Large areas have to be allocated for disposal of them. Thus, waste storage causes environmental pollution and economical loss [3][4][5]. There are many studies on the use of marble and boron wastes as additive or filling materials in various applications such as ceramic [6][7][8], concrete [9][10], brick [11], and building materials [12].…”
