RADAR Calculated vs. TLD Effective Doses to Family Members of Thyroid Cancer Patients Treated with Iodine 131
Journal Title: Macedonian Journal of Medical Sciences (MJMS) - Year 2011, Vol 4, Issue 1
Abstract
Introduction. Patients who receive therapeutic amount of radioactive iodine 131 are significant sources of radiation to their family members, members of the public and others. The situation can be overcome by imposing restrictions on the behavior of the patient to minimize the effective dose to close relatives and not to exceed the proposed dose limits by the International Commission of Radiation Protection (ICRP) and Basic Safety Standards (BSS) from the International Atomic Energy Agency (IAEA). Aim. The aim of this study was to evaluate effective dose to family members of thyroid cancer patients treated with radioiodine 131. Material and Methods. We used thermoluminiscent dosimeters (TLD 100) and RADAR (Radiation Dose Assessment Resource) software for estimation of effective doses. Results. The mean value of effective dose to relatives of thyroid cancer patients was 0.21 mSv. The estimated value of RADAR calculated effective doses for the distance of 0.25, 0.5 m, 1.0 m, 2.0 m were 17 mSv, 4.20 mSv, 1.00 mSv and 0.26 mSv respectively for administered activity of 3700 MBq. Conclusion. Thyroid cancer patients should continue to be treated on in – patient basis to be sure that they will represent minimal radiation hazard for the people in their environment.
