Production of radioisotopes that used in medical diagnosis and treatment are mostly based on the nuclear reactions. The cross-section data are important to understand nuclear reaction mechanisms. In this study TALYS 1.8 code has been used to calculate production cross-sections of Pb, In, F and C radioisotopes at proton induced reactions. Constant Temperature Fermi Gas Model (CTFGM), Back Shifted Fermi Gas Model (BSFGM) and Generalised Super Fluid Model (GSM) have been employed as a level density models for computations. Relative variance calculations have been carried out to determine the best level density model. In addition to cross-section calculations, total activities of radioisotopes have been presented. Production cross-section calculation results have been compared with experimental data taken from Experimental Nuclear Reaction Database (EXFOR).
用于医学诊断和治疗的放射性同位素的生产大多基于核反应。截面数据对于理解核反应机制很重要。在本研究中，TALYS 1.8代码已被用于计算质子诱导反应中铅、铟、氟和碳放射性同位素的生产截面。恒温费米气体模型（CTFGM）、后移费米气体模型（BSFGM）和广义超流体模型（GSM）已被用作计算的能级密度模型。已进行相对方差计算以确定最佳能级密度模型。除了截面计算外，还给出了放射性同位素的总活度。生产截面计算结果已与取自实验核反应数据库（EXFOR）的实验数据进行了比较。
