THE X-/GAMMA-RAYS, PROTON AND ALPHA PARTICLES SHIELDING PROPERTIES FOR TUNGSTEN OXIDE POLYMER COMPOSITES

In this work, the uncharged and charged ionizing radiation shielding properties for tungsten oxide polymer composites amount 9 samples were studied. The uncharged ionizing radiation such as X-rays and gamma-rays shielding properties were simulated at the tube voltages of 40-120 kVp and the energy range of 59.6-1,332 keV, respectively. The mass attenuation coefficients (μm), half value layer (HVL), and mean free path (MFP) values were discussed for both-rays. The charged ionizing radiation such as proton and alpha particles were determined mass stopping power (MSP), and projected range (PR) in the kinetic energy range of 10 keV-10 MeV. The results found that the increasing energy for X-rays and gamma-rays, the μm decreased while HVL and MFP increased. Whereas, increasing tungsten oxide content, the μm increased while HVL and MFP decreased. Also, the HVL was compared with some shielding materials. The result found that the tungsten oxide polymer composites had better X-rays and gamma-rays shielding properties compared to some shielding materials. In addition, the increasing amount of tungsten oxide improved proton and alpha particles shielding. It indicated that the tungsten oxide polymer composites had the ability to shield X-rays and gamma-rays, proton and alpha particles and can be applied as ionizing radiation shielding materials.
