The Measurement of Internal Radiation Dose during Thyroid Cancer Therapy using Iodine 131 by Monte Carlo simulation in Radiation & Isotopes Center of Khartoum (RICK)

Abstract

This study was respective which carried out for Measurement of Internal Radiation Dose during Thyroid Cancer using Iodine 131 by Monte Carlo simulation in Radiation & Isotopes Center of Khartoum (RICK). A sample of 30 adult thyroid cancer patients were investigated over a period of two months.the data required calculation internal dose and effective dose were recorded by the researcher (data sheet). ,and the values calculated analyzed by Microsoft excel. In this study the result were ( for thyroid 759.93 GY with in acceptable tolerance ,esophagus 20.02GY,sivary gland 10.17 GYand the effective dos 35.59GY). The study found that a weak correlation was shown between organ and dose, and there are a strong correlation between thyroid dose and(age, weight and high) and there is strong correlation between time and the activity . The study recommended that daily survey to patient to ensure (that the dose reduction step by step ,patient flow physicist’s order like drink lot of water ,wash his body frequently and supplied the patient by optimal environment during period of it’s isolation in the hospital and ensure that no one from public can get him except especial case which he need it until the dose come down.
