[ 1 ] - محاسبات آهنگ دز ناشی از پرتوزایی طبیعی موجود در سنگ‌های گرانیتی ساختمانی در ایران

All building materials contain various amounts of natural radioactive nuclides. Materials derived from rock and soil contain mainly natural radionuclides of the uranium (238U) and thorium (232Th) series, and the radioactive isotope of potassium (40K). Radiation exposure due to building materials can be divided into external and internal exposure. The external exposure is caused by direct gamma ...
