Abstract |
|
|
| In this work, we have study the radiation dose for shielding properties against gamma ray with energy (662 Kev) emitted from the isotopes of Cs-137 and with Energies (1172 and 1332 KeV) emitted from the isotopes of Co-60. The shielding was content from Epoxy (Ep) resin matrix filled with different concentrations and thickness of Nano-WO3 metal powder as reinforcements. The dose rate and dose reduction percentage of the gamma ray was measured and calculated by using a detector (UltraRadiac™-Plus).Results showed that the highest dose reduction was 46.15% and 34.31% for Cs-137 and Co-60, respectively, at 40% concentration for all samples. We note that dose values decrease with increased concentration and thickness of samples. The polymer is used as a base material for the shield, which increases its strength and elasticity. The additions of nanomaterial have physical characteristics worked attenuation of the radiation. Thus the materials are lightweight and high intensity and suitable for use as shields for gamma radiation. |
