بررسی مقایسه‌ای پاسخ‌دهی و رفتار دزسنج‌های گرماتاب فردی نوترون-گاما در میدان‌های 241Am-Be و 252Cf

Neutron individual dosimetry is challenging subject in dosimetry field. Thermoluminescent dosimeter (TLD) is one of the types of personal dosimeters that is extremely used to determine the doses of neutron sources. Typically, this type of dosimeter is used in different centers with a variety of applications after calibration with a standard neutron radiation sources. Usually, materials of TL crystal that used in personal dosimetry purposes have the effective atomic number of soft tissue such as (LiF). But, importantly, the heavy dependence of the neutron spectrum to geometry of the source location makes the estimation of doses particularly the dose equivalent very difficult. This research is studied on TLD600-700 HARSHAW that used in individual neutron - gamma dosimetry services in Iran. This dosimeters are irradiated with standard sources 241Am-Be and 252Cf at low doses to high doses and their behavior are studied and analyzed. Also the important information about relative response of these dosimeters that irradiated by 241Am-Be and 252Cf sources is presented.
