The production of the most common used PET radioisotope Fluorine-18 with commercial cyclotrons is obtained from the O(p,n)F nuclear reaction when O-enriched water is bombarded with a proton beam. We present the characterization of the secondary neutron field spectra produced by this reaction in different locations around the cyclotron, through a comparison between MCNP6 Monte Carlo simulation results and experimental data obtained with Neutron Activation Analysis (NAA) of thin target foils of different materials.
使用商用回旋加速器生产最常用的正电子发射断层扫描(PET)放射性同位素氟 - 18是通过用质子束轰击富氧水时的O(p,n)F核反应实现的。我们通过比较MCNP6蒙特卡罗模拟结果与用不同材料的薄靶箔进行中子活化分析(NAA)获得的实验数据,展示了该反应在回旋加速器周围不同位置产生的次级中子场谱的特征。
