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.
