Аннотация
Рассмотрено накопление нежелательных долгоживущих радионуклидов при производстве радиофармпрепаратов на основе 18F с использованием циклотрона IBA Cyclone 18/9 HC. С помощью спектрометрии гамма-излучения высокого разрешения с детекторами HPGe проведена идентификация радионуклидов и оценка активности в активируемых компонентах (стриппер, входное окно мишени) «медицинского» 18-Мэв циклотрона IBA Cyclone 18/9. В регенерированной воде идентифицированы более 20 нежелательных радионуклидов. Описаны различные механизмы попадания долгоживущих радионуклидов в облученную воду. Полученные результаты имеют важное значение для оптимизации методов обращения с радиоактивными отходами при производстве радиофармпрепаратов и, как следствие, минимизации дозовых нагрузок персонала.
