[ 1 ] - محاسبۀ ضخامت کمینۀ حفاظ برای اتاق ماموگرافی به‌کمک کد MCNP-4C

In this study MCNP-4C code is used to simulate the least shielding requirements for a mammography room. In order to simulate the X-ray tube, a molybdenum target is irradiated by 28 keV electrons. Then, a molybdenum filter with a thickness of 30 micrometers was used to remove the low-energy parts of X-ray spectrum. Finally the dosimetry evaluations were conducted after designing the lead shield ...
