Abstract

Gold activation foils were used in this work to measure thermal, epithermal and fast neutron fluxes in the 18F, 123I, (201Tl, 67Ga) production units in Syrian cyclotron. The neutron flux distribution around the targets were determined. It shows that, the maze thermalizes the fast neutrons and reduces the flux about four orders of magnitudes. The results can be adopted by medical centers to identify radioactive hot spots and develop radiation protection.

摘要

在这项工作中，使用金活化箔来测量叙利亚回旋加速器中18F、123I、（201Tl、67Ga）生产单元中的热中子、超热中子和快中子通量。确定了靶周围的中子通量分布。结果表明，迷宫使快中子热化，并使通量降低约四个数量级。这些结果可供医疗中心采用，以识别放射性热点并制定辐射防护措施。
