قياس الجرعة الإشعاعية لأمراض الانسمام الدرقي الشائعة لليود المشع 131I باستخدام عدادات التألق الحراري TLDs

Abstract EN

One of the major problem for the toxic Goiter is the estimation of absorbed dose, because the increase or the decrease in the dose negatively affects the treatment of the disease.

In this research a method was proposed to measure the radiation dose for the enlarged region for some of the diseases of the toxic goiter which is common in the northern part of Iraq using (TLD) dosimeter of (LiF) which can be used generally to measure the radiation dose.

It is used here for its great convenience for this disease.

The dosimeters are fixed on the enlarged region of the goiter then the patient takes the dose of 131I.

The proposed method for measure the radiation dose depend on the analysis of decay scheme of 131I and counting the different emitted energies and its percentages combining this theoretical analysis with the reading of the (TLD) the values of the absorbed dose by the enlarged regions.

In this way for measuring the absorbed dose the physician can estimate the future dose.
