Investigation of Beta Radiation Absorption Properties of Tungstate and Molybdate Doped Wallpapers

Abstract

It is very important that the shielding material used in radiation treatment and imaging centers can effectively protect against radiation and that this material is cost-effective. Therefore, studies are underway on the development of different types of shielding materials. In this study, radiation absorption properties of sodium tungstate (Na2WO4) and sodium molybdate (Na2MoO4) coated wall papers were investigated. The beta radiation absorption properties of these elements which are applied on wall papers in different densities (100% precipitated calcium carbonate (PCC), 2.5 g, 5 g, and 7.5 g amounts of Na2WO4 and Na2MoO4 and various thicknesses (0.172-0.258 mm) were investigated. The wallpapers were irradiated with 4 MeV-energized electrons and measurements were taken with the PTW brand electron detector. The linear absorption coefficients of the wallpapers were obtained and half value layer (HVL) and one-tenth value layer (TVL) were calculated from these results. According to the results, it is observed that the beta radiation absorption properties of these wallpapers increase as the density of Na2WO4 and Na2MoO4 increases and as the coating thickness increases in the coating materials used to cover the surface of the wallpapers.

Synthesis of Boron-Doped Zinc Oxide Nanosheets by Using Phyllanthus Emblica Leaf Extract: A Sustainable Environmental Applications

“…Thin films of B-doped ZnO-NSs were synthesized by using the sol-gel process and have been irradiated via the VARIAN ® ( Kavun, 2019 ) linear accelerator. Electrons energized to 6 MeV were applied to thin films placed inside the solid phantoms.…”

“…The D max of 6 MeV electrons necessitated the employment of a 13 mm solid phantom for experiments. A PTW ® ( Kavun, 2019 ) electron detector with a 6 × 6 cm electron field applicator was used to measure the dosage. As shown in Figure 1 , the thin film samples were placed 100 cm from the gantry, and the sensor was positioned somewhere under the material samples.…”

“…The Beer-Lambert Law (Eskalen et al, 2020) is given in Eq. 1, by using this obtained absorption coefficient (μ), the Mass Attenuation Coefficient (Agar, 2018;Kavun et al, 2019) can be calculated, which defines the probability of interaction between gamma photons and mass per unit area.…”
