The attenuation ability of composites containing micro and nano-sized WO3 was measured and compared with the attenuation ability of composites containing micro-size and nano-sized PbO for X-rays in diagnostic energy range. For the purpose, after synthesizing nano and micro-scaled particles, different percentages of them were imbedded in poly vinyl chloride (EPVC) emulsion and prepared as shields with the thickness of about 2mm and exposed to 40-100 kVp range. Transmitted dose, density and mass attenuation coefficient of prepared samples were determined and compared with previous studies. According to the results, the attenuation ability of nano-particle containing shields is better than the ability of micro-particle contained ones. Also the results for WO3 containing samples differ slightly from the results of PbO contained ones. In addition, all of the prepared samples have very lower density than PbO and WO3. Thus, the shields containing nano WO3 are light, flexible and could be a suitable alternative for lead aprons.
