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.
