چکیده

در این پژوهش بعد از ساخت نانوکامپوزیت لاستیک سیلیکون با افزودنی ذرات اکسید بیسموت، قابلیت جذب پرتوی گاما آن مورد بررسی قرار گرفت. با توجه به اینکه زمینه­ی پلیمری و نانو­ذرات در یکدیگر قابل امتزاج بودند، روش فرآوری محلول جهت آماده‌سازی نمونه انتخاب شد و آزمایش میزان تضعیف پرتو گاما در برابر چشمه­ی آمرسیوم صورت گرفت. نتایج آزمایش تضعیف نشان می­دهد که حفاظ­های نانو­کامپوزیتی ساخته شده از کارایی بالایی برخوردار هستند به‌طوری که حفاظ لاستیک سیلیکون – اکسید بیسموت با ضخامت 15/2 میلی‌متر و 70 درصد وزنی پرکننده، 82 درصد فوتون­های چشمه­ی آمرسیوم را جذب می­کند. در نهایت با استفاده از کد مونت‌کارلو برای نمونه­های تهیه شده در مقابل چشمه­ی آمرسیوم شبیه‌سازی انجام شده و نتایج به‌دست‌آمده با نتایج تجربی مقایسه شد؛ که این کد نتایج تجربی را تائید می­کند.

چکیده [English]

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 59.5 KeV. The experimental results showed that the fabricated samples have high performance in low energy X ray shielding. For example, the 70% wt sample with the thickness 0.215cm is able to absorb 82% of photons of 241Am. To verify the experimental results, the attenuation process was simulated by MCNP-4C code and it was found that the simulation coincide with the experiment.
