Estimation of radiation dose received by vital organ in thyroid scintigraphy

Abstract EN

Nuclear medicine (N.M) staff usually received considerable dose during N.M scanning, therefore the estimation of radiation doses received by the forehead, parotid gland and eye lenses (for the thyroid patients) and for the hands, chest and the forehead for the staff; has been considered as objectives in this study.

The study was conducted at Radiation and Isotope Center Khartoum (RICK) A total of 45 patients with thyroid goiter and the staff (3 Technologists) were considered in this study.

The average patient’s surface doses for forehead were 0.10 ± 0.02 mGy, salivary gland (parotid) was 0.09 ± 0.04 mGy and thyroid surface dose was 0.10 ± 0.05 mGy per exam.

The staff radiation dose for the hands was 0.21 ± 0.03, 0.08 ± 0.04 mGy for the chest, and 0.07± 0.05 mGy for the forehead.
