A Theoretical Study on the Production Cross–Section Calculations for 24Na Medical Isotope

Abstract

24 Na is a beta and gamma emitting radioisotope that is widely used in medical field as medical radiotracing. This radioisotope with a half-life of 14.977 hours is mostly produced in cyclotrons. The cross-section of a radioisotope is used to obtain various data about the production of that radioisotope. In cases where it is not possible to obtain experimental data, missing data can be completed with cross-section calculations and the obtained data can be compared with experimental, saving time, cost and effort. This study was carried out for detailed analysis of cross-section calculations for 24 Na isotope, which has a wide range of usage in medicine. In this direction, the cross-sections obtained from different computation programs were compared with literature data of the reactions. Production cross-sections of the 24 Na isotope were investigated in the 23 Na(d,p) 24 Na, 24 Mg(n,p) 24 Na, 25 Mg(n,n+p) 24 Na, 25 Mg(p,2p) 24 Na, 26 Mg(d,α) 24 Na and 27 Al(n,α) 24 Na reactions with the equilibrium and pre-equilibrium models of nuclear reaction codes of TALYS 1.95 and EMPIRE 3.2. Results were compared with experimental data from the EXFOR data library. The relevance of the models to the reactions was discussed and calculations were made using the relative variance analysis method to determine the most consistent model.

Cross-Section Calculations of Medical Radioisotope 64Cu via some Proton, Neutron and Deuteron Reactions

“…Many calculation programs are available to receive the cross-section data of various reactions; TALYS and EMPIRE, used in this study, are two of them. Various nuclear reaction programs are used in many studies in the literature, where more experimental data are needed to determine suitable calculation methods [21][22][23][24][25][26][27][28][29][30].…”

Investigation of the Effects of Optical Models on the Production Cross–Section Calculations of 22,24Na Radioisotopes with some (d,x) and (α,x) Reactions

“…Given the characteristic properties of 22 Na, its usage for a number of applications and differ purposes, such as calibration in positron emission tomography (PET) imaging systems, has emerged [33][34][35][36]. On the other side, 24 Na has been demonstrated to be useful in studies on bone blood flow, postmastectomy lymphedema, intramuscular clinical trials, and noradrenaline sensitivity in hypertension [37][38][39][40][41]. Apart from these studies, it is possible to encounter examples of studies on the use of both radioisotopes for different purposes in the literature [42][43][44][45].…”

Effects of Deuteron and Alpha Optical Model Potentials on the Production Cross–Section Calculations of Some Radiobromine Isotopes

“…Level density models, gamma strength functions, deuteron and alpha optical model potentials can be given as examples. Studies examining the use of these models and parameters independently or in combination to produce results that are more compatible with experimental data also contribute to the literature [11][12][13][14][15][16][17][18][19][20]. The motivation of this study was created in this conjuncture.…”
