Abstract

Objective: It is aimed to determine the radiation doses to which radiation workers working in radionuclide treatments in nuclear medicine are exposed in the long term and to determine the contribution of each routine treatment procedure to these doses. Materials and Methods: The personal dosimetry records of doctors, nurses, health physicists, radiopharmacists, and cleaning staff, who routinely applied 131I treatment, 177Lu treatment, 90Y microsphere treatment, and 131I MIBG treatments were retrospectively analyzed for 6 years. The number of treatments performed in the same period and the persons assigned to these treatments were determined. Absorbed radiation doses of radiation workers in treatments and dose values per procedure were deduced from this information. Results: The highest average annual radiation dose was found to be 2185±1839 μSv in radiopharmacists. It was calculated as 786±943 μSv in nurses, 753±706 μSv in health physicists, 626±741 μSv in doctors and 961±1099 μSv in cleaning staff. The mean dose values calculated per procedure were found to be 129±208 μSv in the highest physicians. It was found 122±187 μSv in nurses, 76±122 μSv in health physicists, 76±52 μSv in radiopharmacists, and 42±64 μSv in cleaning staff. Conclusion: It was demonstrated that the annual radiation doses were within the permissible safe values and there was no excessive radiation exposure during radiopharmaceuticals preparation, administration to patients, and during the patients’ stay in the therapy unit.

Özet

Amaç: Nükleer tıpta radyonüklit tedavilerde çalışan radyasyon görevlilerinin uzun dönemde maruz kaldığı radyasyon dozlarının belirlenmesi ve rutin olarak yapılan her bir tedavi prosedürünün bu dozlara katkısının belirlenmesi amaçlanmıştır. Gereç ve Yöntem: 6 yıl boyunca rutin olarak İyot-131 (131I) tedavisi, (Lutesyum-177 (177Lu) tedavisi, Yittrium-90 (90Y) mikrosfer tedavisi ve 131I MIBG (Meta-İyodobenzilguanidin) tedavisi uygulayan doktor, hemşire, sağlık fizikçisi, radyofarmasist ve temizlik personelinin kişisel dozimetri kayıtları geriye dönük olarak incelendi. Aynı dönemde gerçekleştirilmiş olan tedavi sayıları ve bu tedavilerde görevli olanlar belirlendi. Bu bilgilerden radyasyon görevlilerinin tedavilerdeki absorbe radyasyon dozları ile prosedür başına doz değerleri çıkarıldı. Bulgular: Yıllık ortalama radyasyon dozları en yüksek radyofarmasistlerde 2185±1839 μSv bulundu. Hemşirelerde 786±943 μSv, sağlık fizikçilerinde 753±706 μSv, doktorlarda 626±741 μSv ve temizlik görevlisi personellerde 961±1099 μSv olarak hesaplandı. Prosedür başına hesaplanan ortalama doz değerleri en yüksek doktorlarda 129±208 μSv olarak bulundu. Hemşirelerde 122±187 μSv, sağlık fizikçilerinde 76±122 μSv, radyofarmasistlerde 76±52 μSv, temizlik görevlisi personellerde 42±64 μSv bulundu. Sonuç: Radyofarmasötiklerin hazırlanması sırasında, hastaya uygulanması sırasında ve hastanın tedavi servisinde yattığı süre boyunca doz aşımı olmamış, belirlenen radyasyon dozlarının izin verilen güvenli değerlerde olduğu tespit edilmiştir.
