In this study, barium (Ba) doped nano-bismuth tungstate was prepared by the hydrothermal method. In order to characterize the sample, X-ray diffraction (XRD and EDX) and field emission scanning electron microscopy (FESEM) were applied. The aqueous solution of the prepared sample with different concentrations of nano-bismuth tungstate oxide doped with barium oxide along with hydroxyapatite (HAP) and poly (vinyl alcohol) (PVA) was coated on the cotton fabrics by the pad-dry-cure method. The results showed that the raw cotton sample had the highest air permeability of 157 cc/sec and the P10B40H20 sample had the lowest air permeability of 94 cc/sec. In the other hand, PVA resin on the samples leads to a decrease in fabric comfort, but barium-doped bismuth tungstate nanoparticles and hydroxyapatite do not have any significant effect on this factor. The radiation shielding results showed that the increase of three material concentrations led to an increase in the radiation shielding properties. The highest attenuation of radium radiation was found in the P10B40H20 sample with a 73.23 attenuation percentage, and the lowest attenuation was found in the raw sample with a percentage of 58.59. Also, samples containing PVA have the highest washing fastness.
