    The Effect of I-131 Treatment on Complete Blood Count
    (Natl Atomic Energy Agency Indonesia, 2024) Sahutoglu, G.; Cetin, S. K.; Atilgan, H. I.
    Radioactive iodine -131 (RAI) treatment may cause suppression in the bone marrow. In this study, hemoglobin levels, leukocyte, thrombocyte, and lymphocyte counts will be compared before total thyroidectomy and 6 months after RAI treatment. 97 patients (76 females, 21 males) with a diagnosis of well -differentiated thyroid cancer who had undergone total thyroidectomy and received 50-200 mCi RAI treatment were included in the study. Hemoglobin levels, leukocyte, thrombocyte, and lymphocyte counts of the patients in the last month before the treatment and in the sixth month after the treatment were compared retrospectively. When the whole patients were analyzed, hemoglobin levels, leukocyte, thrombocyte, and lymphocyte counts in pretreatment were statistically lower than after -treatment values. While hemoglobin levels of female patients were similar before and after treatment, lymphocyte, thrombocyte, and leukocyte counts were statistically lower before treatment. Hemoglobin levels, leukocyte,and thrombocyte counts were similar before and after treatment, while lymphocytes decreased significantly after RAI treatment. Thyroid cancer patients who received 50-200 mCi RAI treatment after total thyroidectomy, have bone marrow suppression but are still in normal mean value ranges. This mild bone marrow suppression is more prominent in female patients than in male patients. (c) 2024 Atom Indonesia. All rights reserved

    AN EVALUATION OF THE OCCUPATIONAL EXTERNAL RADIATION EXPOSURE OF PERSONNEL IN NUCLEAR MEDICINE PRACTICES (2010-2020)
    (Oxford Univ Press, 2022) Sahmaran, T.; Atilgan, H., I; Nur, S.; Sahutoglu, G.; Yalcin, H.
    The aim of this study was to examine the radiation doses received by personnel working in the Nuclear Medicine Department between 2010 and 2020. The data obtained were compared with the dosages recommended by international authorities. The UNSCEAR 2008 report stated that the worldwide annual average effective dose to which personnel were exposed when monitored between 2000 and 2002 was 0.70 and 1.40 mSv, respectively. In this report, 0.7 mSv refers to the dose of all monitored personnel, and 1.4 mSv refers to the dose above the detection limit. In this study, the annual average effective dose value for personnel exposed to radiation was calculated as 1.65 mSv. This value represents the dose above the detection limit. Although the individual dose results are below the recommended annual dose limit, it should not be forgotten that more effort should be made to reduce radiation doses using the as low as reasonable achievable principles.
