[ 1 ] - ساخت، مشخصه‌یابی و شبیه‌سازی خواص حفاظت در برابر پرتوی گامای نانو‌کامپوزیت لاستیک سیلیکون آمیخته با نانو‌ذرات اکسید بیسموت

By use of silicon rubber as polymeric matrix and bismuth oxide as fillers, composite materials were fabricated up to 70 wt% and their gamma ray attenuation was studied. Due to the fair solubility of bismuth oxide particles in polymer matrix, the solution intercalation method is used for nanocomposite fabrication. The applied source for radiation attenuation test was 241Am with photon energies 5...
