PET cyclotrons are widely used for producing medical diagnostic radionuclides. The main radionuclide produced in these facilities is the 18F, which is obtained from the [18O (p,n)18F] reaction when 18O-enriched water is bombarded with the proton beams. This work aimed to estimate the radiation source term from the bombardment of an 18O-enriched water target with protons of 16.5 MeV to determine the radiation neutron field around the accelerator.
正电子发射断层扫描(PET)回旋加速器被广泛用于生产医学诊断用放射性核素。这些设施中主要生产的放射性核素是 18F,其通过用质子束轰击 18O 富集水发生 18O(p,n)18F 反应获得。本工作旨在通过 16.5 MeV 质子轰击 18O 富集水靶,估算辐射源项,以确定加速器周围的辐射中子场。
