“…Generally heavy filler materials are used with polymer matrixes like metals and metal oxides [1,2,4]. There are also numerous studies in which several natural minerals are used as filler materials for the composite IEMR shielding like serpentine, hematite and limonite [5][6][7]. A comprehensive literature review revealed that the potential IEMR shielding properties of natural mineral filled composites were investigated only with cement matrixes.…”

In the study, usability of natural titanium-iron oxide filler for ionizing electromagnetic radiation (IEMR) shielding composites with isophthalic polyester (PES) matrix was investigated for the first time. Shielding performances of the composites were also investigated for three different IEMR energy regions as low, intermediate and high for the first time, too. Mass attenuation coefficient of prepared composite with the best shielding performance reached 80 % of elemental lead's performance at low energy regions while it had higher mass attenuation coefficient at intermediate and high energies.

“…Quite a few studies have dealt with the shielding properties and the leakage spectra of heavy weight concrete made from Egyptian heavy weight aggregate such as El-Shinawy (1975), Hafez et al (1988), Sakr (1988), Bashter et al (1995), and Makarious et al (1995).…”

Petrographic, physical, chemical, mechanical, and radioactive characteristics tests were performed on magnetite, limonite, and hematite found in abundance in Egypt to determine their suitability for producing radiation shielding concrete. The contents of uranium and thorium were determined using instrumental neutron activation analysis and gamma spectroscopy. The results obtained using the two methods have shown satisfactory correlation. The tests confirm that magnetite and limonite are suitable as concrete aggregate while hematite is not because of its friable nature and high contents of uranium, thorium, and cobalt.

“…Using these radioactive isotopes can cause dangerous damage of the workers and exposures tissues (Gençel et al, 2010;Mann et al, 2016). For radiation protection inside houses, factories and hospitals, the building materials used must provide adequate protection for workers at a reasonable cost (Bashter et al, 1996). The mass attenuation coefficient provides information about gamma ray penetration and the amount of energy deposited inside the exposed materials.…”

This study points to evaluate the effect of crushed basalt grain size and the press rate on gamma ray shielding properties for some concretes. Nine different concretes were made up of 75% basalt, 25% Portland cement and drops of sodium meta silicate. Three concretes were performed with an average grain size varied between 25 and 107 μm. The other six concretes were performed under different press rate varied between 1.01 and 142.76 kg/ cm 2 using a hydraulic press. The mass attenuation coefficient (μ m ) of the prepared concretes was measured using the narrow beam transmission method using a hyper pure germanium detector at gamma ray energies 661.6,
