Sale price: $5.00


The Effective doses (ED) received by caregivers of patients on 131I (iodine-131) treatment for cancers of the thyroid have been measured. The measurements were carried at the Nuclear Medicine Department of University College Hospital (UCH), Ibadan. High sensitivity tissue equivalent thermo luminescent dosimeters (TLDs) were used for measuring the doses received by 25 caregivers who assisted 7 patients treated with various doses of 131I (Iodine-131). The number of caregivers who supported the treated patients was between 2 and 5 caregivers per patient. The mean doses received by the caregivers ranged from 0.11 to 0.92 mSv per patient.  Additionally, the mean doses received by teenagers, young adults and adults were 0.31, 0.34 and 0.24 mSv respectively. The mean dose received by the caregivers is below the limit of 5.0 mSv recommended by the US Nuclear Regulatory Commission indicating that the caregivers considered in this study are at lower radiological health risk. The trend in this study shows that low doses could be achieved with adequate restriction and compliance with the safety instruction in developing countries.
